What should come in place of the question mark (?) in the given series based on the English alphabetical order?
MPI, KNG, ILE, GJC, ?

MPI, KNG, ILE, GJC,  ?

Logic: 1st - 2, 2nd - 2, 3rd -2 

M − 2 → K, K − 2 → I, I − 2 → G, G − 2 → E
P − 2 → N, N − 2 → L, L − 2 → J, J − 2 → H
I − 2 → G, G − 2 → E, E − 2 → C, C − 2 → A

So EHA is the missing term.

Thus, correct option is (a).
