If you do not understand the meaning of a question in an interview, what is the most appropriate response?

Correct answer: Politely ask the interviewer to repeat or clarify the question

Politely requesting repetition or clarification ensures that the candidate answers the question actually asked rather than an imagined one. It demonstrates honesty, active listening, and professional communication. A guess may produce an irrelevant answer, silence gives no useful response, and changing the topic appears evasive. Therefore, option A is the most appropriate interview behaviour.
