B) Begins with and is centered in the mutual interaction of community members

Explanation:

Let's take one by one to better understand why the correct one is B.

NOTE: I make a direct relationship between social thinking and social sciences, i hope it works for you.

A) As you may know, social sciences are not exact sciences such as physics or chemistry: in social sciences there are not some few rules that let you, as an investigator, understand all the phenomena in question. For being a social investigator you must go out and see the world and the interaction's between the people and the bonds they create. Solitary study and reflection may work for philosophers or physicists, but not for social investigators.

C) Well, this may be true in some people but is not very common, let's face it: not everybody is concerned in "acting for the common good" ... if we all were, we would live in a much better world.

D) Same as C, it may happen, but not every social investigator cares about that ... or in other words: to be a social investigator is not necessary that tou concern about better alternative realities.

The only real option is B) which shows how important it is for the social investigator to go out and study the community interactions he or she is interested in.
