Answer: B . A B P U S

Justification:

The male advocates are A and B, lady doctors are P, Q and S; teachers are E, T and U.
Now, A and B will be selected.
A, P and U have to be together.
Now, we have to select one lady doctor more. It can be Q or S. But Q and E have to be together. Since  E is not selected, so S will be selected.
Thus, the term is A B P U S.
