If including P, the team has three girls, the members are :
Answer: A
If P is included, D and hence A cannot be included.
If Q is selected, C has to be selected and so S cannot be selected.
T goes with S. So, T is also not selected.
The third girl can be R. With R, B will be selected but with B, E cannot be selected. So, the sixth member can be F only. i.e, the team become P Q C R B F. So, the answer is (a).
