What should come in place of '?' in the given series based on the English alphabeticalorder?

EIK, IGJ, MEI, QCH, ?

Given: EIK, IGJ, MEI, QCH, ?

Logic: 1st letter + 4, 2nd letter - 2 and 3rd letter - 1 place.

For, 1st letter

E + 4 → I, I + 4 → M, M + 4 → Q, Q + 4 → U

For, 2nd letter

I - 2 → G, G - 2 → E, E - 2 → C, C - 2 → A

For, 3rd letter

K - 1 → J, J - 1 → I, I - 1 → H, H - 1 → G

So, the missing term is UAG.

Thus, correct option is (d).
