From amongst five doctors A, B, C, D and E, four engineers G, H, K and L and six teachers M, N, O, P, Q and R, some teams are to be selected. Of these, A, B, G, H, O, P and Q are females and the rest are males.

The formation of teams is subject to the following conditions :

Wherever there is a male doctor, there will be no female teacher.

Wherever there is a male engineer, there will be no female doctor.

There shall not be more than two male teachers in any team.

**If the team consists of two doctors, one engineer and four teachers, all the following teams are possible except :**

** Option:**

**A.**A B G M N O P

**B.**A B H M O P Q

**C.**A B H M R P Q

**D.**A B K N R P Q

**Answer: D . A B K N R P Q**

** Justification:**

The doctors are A, B, C, D and E; engineers are G, H, K and L; teachers are M, N, O, P, Q and R. Four teachers are needed. There are three male teachers. So, female teachers are also to be selected. So, male doctors i.e. C, D and E cannot be selected. Thus, the two docotors selected will be A and B.

Both the doctors selected are females. So, male engineer K or L cannot be selected and either G or H is to be chosen.

Clearly, the impossible team is A B K N R P Q, because K is not to be selected.
