Answer:
B. Affiliation.
Explanation:
Affiliation can be defined as the act of becoming formally connected or joined. Doug would like to be affiliated with Carrie, and so he wants to get to know her better. This is not validation, as validation is typically used to describe when a person is trying to fit in to a certain group (or the general public), as he wants to be validated or become part of that group. This can include being peer pressured into doing the latest trend that everybody is doing, for example.
