The correct answer is: Leading
Rationale: A leading question pushes the interviewee to give a certain answer. (In this case, it is obvious that the interviewer expects the interviewee to agree.)
An open question requires self-expression; a closed question invites a one word either/or answer, and a problem-solving question presents candidates with a situation and asks them to say how they would deal with it.
Pitfalls: This is an easy aspect of interviewing technique to set questions on: make sure you can identify all types of questions.
