English

The idiom "to smell a rat" means to suspect that something is wrong or that there is foul play involved. Therefore, option C correctly captures the meaning of the phrase.

The phrase "elephant in the room" refers to an obvious problem or issue that everyone is aware of but chooses to ignore or avoid discussing, usually because it is uncomfortable or sensitive. Option A accurately captures this meaning.

The phrase "cap it all" (often "to cap it all off") means to finish or complete something, often by adding a final element that tops or sums up all previous points. It can also mean to surpass or outdo something. This usage is supported by authoritative sources like Cambridge Dictionary, Dictionary.com, and Collins Dictionary, which define it as finishing or completing an experience or situation, often with a final touch. Therefore, the most accurate meaning among the options is "To finish."

The word 'Irreverenced' means showing a lack of respect or reverence. Among the options, 'Disrespect' is the closest synonym, as it directly conveys the absence of respect.

The phrase "get your goat" is an idiom meaning to irritate or annoy someone. Therefore, option B is correct as it directly matches the idiomatic meaning.

The phrase "drop a dime" is an idiomatic expression meaning to inform on someone or act as an informant, especially to the authorities. This matches option A exactly.

The phrase "a hot potato" refers to a controversial or awkward issue that people want to avoid dealing with, making option D the correct meaning. The other options do not accurately reflect the idiomatic usage of the phrase.

The correct phrase is "The girl stood in the burning house." The article "The" is appropriate to specify a particular girl, and the preposition "in" is correct to indicate that the girl is inside the burning house. The preposition "on" would imply standing on the surface of the house, which is less likely and unusual in this context. Option D is incorrect because it lacks the article before "Girl." Therefore, option C is the grammatically correct and contextually appropriate choice.

The word "accolade" means an award or an expression of praise and honor, so the synonym is "honor." The other options do not relate to the meaning of "accolade."

The phrase "icing (also frosting) on the cake" refers to an attractive but inessential addition or enhancement that makes something already good even better, which matches option D.
