The single most important factor in whom you will become friends with is:

a. proximity.
b. shared values.
c. equal attractiveness.
d. social background.

Proximity...the people with whom you have the most contact.

The correct answer is A. Proximity.

Explanation:

The proximity principle consists of the ability that individuals have to establish relationships with people who are close to them. It is said that there are two reasons why people establish groups with those who are close to them rather than those who are far away. The first reason is that people like to interact with things that they consider as familiar and the second reason is that when there is frequent interaction between people, relationships can be established easily.

Proximity allows an appropriate interaction between groups as well as individuals and it also allows them to share interests and have good relationships.
