Select the letter cluster which does not belong to the same group from the given alternatives.

The logic followed here is as follows: In each letter cluster, the 2nd letter is the 3rd succeeding letter of the 1st letter and the 3rd letter is the 5 th succeeding letter of the 2nd letter. For option 'A', 'KNS': K + 3 = N, N + 5 = S For option 'B', 'DGL': D + 3 = G, G + 5 = L For option 'C', 'ILQ': I + 3 = L, L + 5 = Q For option 'D', 'VYE': V + 3 = Y, Y + 5 = D ≠ E All the letter-cluster, except the letter-cluster given in option 'D', follows the same logic.
