Correct Answer:
B. to
The adjective "averse" means having a strong dislike of or opposition to something. In English grammar, "averse" is almost invariably followed by the preposition "to." This forms a common and correct idiomatic expression: "averse to something." Therefore, "He is averse to hard work" correctly conveys that he dislikes or is opposed to hard work.
- "from" is incorrect; while "avert from" exists, it means to turn away, not to dislike.
- "of" is grammatically incorrect in this context; "averse of" is not a standard collocation.
- "with" is also incorrect; "averse with" does not form a meaningful or grammatically sound phrase in English.
