The agenda behind this question is to understand if you are a team player or a solo performer.

It might be risky to choose any one of them as the role for which they are considering you might need you to be a team player but the career progression which they might consider for you down a year’s time may need you to handle a more autonomous position.

It is better to answer this question by saying that “I don’t have any such preference. I can comfortably handle both the situations, as the need arises.” Now back it up with examples where you successfully worked in a team and where you performed an autonomous role.
