All of the following are types of dorm rooms except a. coed b. suite quads c. single-sex d. fraternities or sororities

The answer is D

Options A, B, and C are all types of dorms rooms.

Coed by rooms: Majority of dorms are coed by room. This means that guys and girls can share walls but not rooms. In many cases, it is more exciting to be in coed dorm since they eliminated the mystique of the opposite sex.

Suite Quads: Most first year students have at least one roommate and thus, the double is the most common arrangement. As enrollment rises and the number of students increase, these doubles are often turned into triples and quads

Single-sex: There are fewer all-male dominated dorms than all female. The disadvantage of single sex dorms is the fun part. It is more exciting being in a coed dorm than in single gender dorms.
