A characteristic of a closed question in an interview is that the answer choices are typically limited, often to "yes" or "no." Closed questions are designed to elicit specific information and usually restrict the respondent’s answer to a predefined set of options.
In contrast, if a question asks for an explanation or is very broad, it invites more elaborate responses and is thus more open in nature. Respondents are also likely to have fewer constraints with open questions, allowing for a wider range of answers.
So, among the options provided, the characteristic that aligns with a closed question is "the answer choices are yes or no."
