Question

what type of questions are best to ask of peers?
which job best fits their interests

Explanation:

Peers are likely to share their own college - life experiences, so asking "what college life is like" is appropriate. Questions about which job fits interests or which college to attend after graduation are more suitable for mentors or career counselors as peers may not have enough expertise or experience in these areas.

Answer:

C. what college life is like (assuming the options are labeled A, B, C as per the order: A. which job best fits their interests, B. which college to attend after graduation, C. what college life is like)
