B) C,D,K,L,O,P,Q

C) C,D,O,P,Q,G,H

D) D,E,G,HO,P,Q

Answer:

Option A

Explanation:

The doctors are A, B, C, D and E; female teachers are o, P and Q; engineers are G, H, K and L. The three female teachers to be selected are O, P and Q. Now, wherever there is a male doctor, there will be no female teacher. But three female teachers are selected. So, C, D and E can not be selected. Thus, the two doctors selected are A and B. Since female doctors are selected, so male engineers K and L cannot be selected. Hence, the team formed is A, B, O, P, Q, G, H.
