If the team consists of two doctors, female teachers and two engineers, all the following teams are possible except :
Answer: B
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
