Adi and Liana are both from Indonesia. They have many things in common like language, traditions, values, and customs. Even so, Adi is still not close friends with Liana. They have different religious beliefs. Adi feels an emotional connection to people that share his religious beliefs and no affiliation to those who don't. Adi does feel an emotional connection to Miguel, although he is from South America, because they both share religious beliefs. What choice below best characterizes Adi's relationships with Liana and Miguel?

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).
