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, female teachers and two engineers, all the following teams are possible except :**

** Option:**

**A.**A B G H O Q

**B.**A B G H P Q

**C.**A B K L P Q

**D.**O P G H A B

**Answer: C . A B K L P Q**

** Justification:**

The doctors are A, B, C, D and E; female teachers are O, P and Q; engineers are G, H, K and L. Since two female teachers are 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 are females. So, male engineer k or L cannot be selected and G and H are to be chosen.

Clearly, the only impossible team is A B K L P Q.
