Which term refers to the act of avoiding answering a question?

The term that refers to the act of avoiding answering a question is "evasion." Evasion typically implies a deliberate attempt to avoid giving a direct answer or to escape from a situation where one is expected to respond. This can occur in various contexts, such as during an interrogation or a legal proceeding, where a person may choose not to answer directly in order to dodge scrutiny or responsibility.

Inquisition refers to a formal questioning or investigation, often associated with legal or religious scrutiny. Admission involves acknowledging or agreeing to something, particularly in response to questioning. Submission denotes yielding to someone else's authority or control, which is not directly related to avoiding an answer. Thus, evasion is the most accurate term for the act of not responding directly to a question.
