A clique is a small group of people

A. Who are part of an extended family
B. Who have similar backgrounds and interests
C. Who value each others differences
D. Who are all the same age

B. Who have similar backgrounds and interests

B. Who have similar backgrounds and interests

The correct answer to the question is B. A clique is a small group of people who have similar backgrounds and interests.

To arrive at this answer, we can analyze and eliminate the incorrect options:

A. "Who are part of an extended family": This option is not the defining characteristic of a clique. While some cliques may include family members, the concept of a clique is not limited to an extended family.

C. "Who value each other's differences": While it's possible for a clique to value each other's differences, this is not a defining characteristic. A clique is primarily formed based on shared backgrounds and interests, rather than valuing differences.

D. "Who are all the same age": This option is incorrect because a clique can include people of different ages. Age is not a determining factor for a clique.

Therefore, the correct answer is B. "Who have similar backgrounds and interests," as this option best captures the defining characteristic of a clique as a small group of people with shared backgrounds and interests.
