English

The synonym of 'backbone' is 'spine' as both refer to the vertebral column. 'Back' is related but not a direct synonym, and 'front bone' is incorrect. Therefore, option B is the correct answer.

Option C is the grammatically correct passive construction of the sentence, using 'was realized' to indicate the past realization. The other options contain grammatical errors such as incorrect verb forms, wrong word usage ('quiet' instead of 'quite'), or misspellings ('ere' instead of 'were').

The term 'henpeck' refers to a man who is dominated or controlled by his wife, making option A the correct answer. The other options do not relate to this meaning.

The word 'adapt' means to adjust or modify to suit new conditions. The antonym would be a word that means unable to adjust or unsuitable, which is best captured by 'Unfit'. The other options do not relate to the meaning of 'adapt'.

The past tense of "find" is "found." "Founded" is the past tense of "found" meaning to establish, which is a different verb. Therefore, option B is correct.

The word 'infringe' means to violate or break a rule or law, which is synonymous with 'breach'. The other options do not share this meaning.

The term 'constellation' literally refers to a group or pattern of stars forming a recognizable shape in the sky. Figuratively, it is used to describe a group or collection of associated or similar things, often implying that these elements form a meaningful pattern or configuration. This metaphorical use is supported by dictionary definitions and language usage examples, where 'constellation' can mean a group of related people, things, qualities, or factors that together produce an effect or represent a situation. The other options do not fit this definition.

The word 'kidnap' means to abduct or take someone away illegally by force. Among the options, 'Abduct' is the correct synonym. 'Appalling' means shocking or horrifying, and 'Renounce' means to give up a claim or right, so they are incorrect. 'All the above' is incorrect because not all options are synonyms.

The phrase 'I'm getting late _____ office' is not idiomatic English. The correct and natural way to express this idea is 'I'm getting late for the office.' The preposition 'for' is used to indicate the destination or purpose when talking about being late. The option 'to' is incorrect in this context. According to standard English usage, 'late for' is the correct collocation when referring to being late to a place or event.

The correct sentence is 'Afridi plays the harmonium and the sitar is played by him also.' This is because the second part of the sentence is in passive voice and requires the object pronoun 'him' after 'played by' to be grammatically correct. Option C 'Played by him' correctly completes the sentence. Option A 'Played' is incomplete and grammatically incorrect in this context. Option B 'Played by he' is incorrect because 'he' is a subject pronoun and cannot be used as the object of the preposition 'by'. Option D 'None of these' is incorrect as option C is the correct choice.

The correct phrase is "there is a limit to everything in life." The preposition "to" is standard and most commonly used in this expression to indicate a boundary or maximum extent. While "limit on" can be used in contexts emphasizing an imposed restriction, "limit to" is the natural and idiomatic choice in this phrase. The options "in" and "with" are incorrect in this context.

Claustrophobia is the fear of closed or confined spaces, making option A the correct answer. The other options do not relate to this fear.

Matricide is the act of killing one's mother. Parricide refers to killing a close relative, regicide is killing a king, and patricide is killing one's father, so the correct term for killing one's mother is matricide.

A 'tyrant' is a cruel and oppressive ruler, and a 'persecutor' is someone who oppresses or harasses others, making 'Persecuter' the closest synonym among the options. The other options do not relate to the meaning of 'tyrant'.

The sentence refers to a specific action completed in the past ('yesterday'), so the simple past tense 'saw' is correct. 'Have seen' is present perfect and does not fit with a definite past time expression. 'Had seen' is past perfect, which is not appropriate here, and 'seen' alone is not a correct verb form without an auxiliary.

The term 'regicide' specifically refers to the act of killing a king. Other options refer to different types of killing: 'suicide' is killing oneself, 'patricide' is killing one's father, and 'parricide' is killing a close relative or parent.

The term 'brittle' describes something that is easily broken or cracked under stress. 'Resilient' means able to recover quickly, and 'flexible' means able to bend without breaking, so 'brittle' is the correct choice.

The word 'brusque' means abrupt or blunt in manner. Its antonym is 'courteous,' which means polite and respectful, making option D the correct answer.

The correct adverb to modify 'pleased' in this context is 'very,' which appropriately intensifies the adjective. 'Much' is less commonly used before adjectives like 'pleased,' 'too' implies excessiveness, and 'none' is not an adverb.
