The correct option is C A, B, K, L, P, Q
The Delhiites are A, B, C, D and E; software programmers from Maharashtra are O, P and Q; Tamilians are G, H, K and L. Since two software programmers from Maharashtra are to be selected, so manager from Delhi i.e. C, D and E cannot be selected. Thus, the two Delhiites selected will be A and B. Both the Delhiites are software programmers. So, Tamilian manager 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.
