Correct Answer:
A. to
When "deaf" is used metaphorically to indicate an unwillingness to listen or pay attention to something, the correct preposition to use is "to". The phrase "deaf to my advice" means that the person is ignoring or refusing to consider the advice given. This is a common idiomatic expression in English.
- for: Not used in this specific metaphorical context.
- of: While "deaf of one ear" can be heard, it's less common and not applicable to advice.
- from: Used to indicate the cause or origin of deafness (e.g., "deaf from birth"), not an unwillingness to listen.
