In an interview, a candidate begins every answer with a very long introduction. How can effectiveness be improved?

Correct answer: By giving the main answer first and then necessary details

The governing principle is concise, audience-centred verbal communication. In an interview, the listener should understand the candidate’s main point quickly; supporting details can follow in a relevant order. Option B is correct because it gives the answer first and preserves useful explanation without burying the point. Adding more introductory detail, refusing to answer, or forcing equal length would reduce clarity and relevance.
