Collective nouns, in language, refer to a collection of things taken as a whole. Since they are taken as a whole, or one unit, they are almost always singular.

A. they had in any previous year
B. their previous years had had
C. they had for any previous year
D. in their previous years

“Team” is singular on the GMAT, a collective noun, so we can eliminate (A), (B), (C), and (D) right away. This should be an easy-question for anyone who has a good grasp on Pronouns.
