When converting direct speech to reported speech, the present or future tense usually changes to the past or conditional tense, and time expressions like 'tomorrow' change to 'the next day'. Therefore, 'I will meet you tomorrow' becomes 'he would meet me the next day' in reported speech.

The idiom 'up to the hilt' means to the utmost extent or completely, fully involved or committed to something. It originates from the image of a sword plunged into something so deeply that only the handle (the hilt) remains visible. This fits the context of being very busy with work. The other options are either incorrect or irrelevant idioms in this context.

Both 'Disavow' and 'Renounce' mean to reject or give up something, which are synonyms of 'Abjure'. 'Espouse' means to adopt or support, which is the opposite.

"Perdition" means a state of eternal punishment or damnation, often synonymous with hell or doom. "Heaven" is the opposite (antonym) of perdition, while "doom," "hell," and "infernal" are synonyms or related to perdition.

The word 'abjure' means to renounce or reject something formally. Its antonyms include 'espouse' and 'support,' both meaning to adopt or advocate for something. Therefore, both options A and B are correct antonyms, making option C ('Both a&b') the correct answer.

The word 'flaunt' means to show off or display something ostentatiously. 'Cover' is the antonym because it means to hide or conceal, whereas 'brandish', 'display', and 'exhibit' are synonyms meaning to show or present something.
