Answer:
A. Adi is in an in-group with Miguel because they share religious beliefs and Liana is in an out-group with Adi because they do not share religious beliefs.
Explanation:
Since Adi shares the same religious belief with Miguel, the both of them are in an in-group (of same religious belief).
Also, since Liana does not share the same religious belief with Adi, the both of them are in an out-group.
An in-group is simply a small group of individuals who share a particular interest i.e they share something in common.
An out-group is a group who do not have an in-group (they do not share a particular interest together).
