Please tell me what you think is the correct answer:

Membership in the Theta Delta Psi fraternity is easily obtained by those who have a previously had strong social connections with existing fraternity members before college. However, one must have attended high school with one or more of the members in order to forge such strong social connections. People who lack these social connections because they have not attended high school with one or more current fraternity members will therefore find it difficult to join the fraternity.

This argument displays flawed reasoning because it neglects to consider the possibility that
A) many of those who went to high school with TDO fraternity members did not themselves become members of the fraternity
B) it is more important in the long run to socialise with non-fraternity members than to develop strong connections with fraternity members
C) it is more difficult to forge social connections with fraternity members than with non-fraternity members
D) one may easily obtain membership in the fraternity through means other than having strong social connections with existing members
E) some current members of the fraternity did not go to high school with other members
