What kind of language should be used while answering in an interview?

Correct answer: Clear and polite

The governing concept is appropriate verbal communication in a formal interview. Clear language helps the interviewer understand the answer, while polite language shows respect, self-control, and professionalism. Option A is correct because it combines both qualities and keeps the response suitable for the situation. Unclear or rude language can create misunderstanding, excessive informality may seem unprofessional, and an irrelevant answer does not address the question.
