    Question

    Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
    KDWP, PIBU, UNGZ, ZSLE, ?

    A.

    ERTD

    B.

    EQJX

    C.

    EDRT

    D.

    EXQJ

    Correct option is D

    Given: KDWP, PIBU, UNGZ, ZSLE, ?
    Logic: Letters are increasing + 5 place.
    K + 5 = P, P + 5 = U, U + 5 = Z, Z + 5 = E
    D + 5 = I, I + 5 = N, N + 5 = S, S + 5 = X
    W + 5 = B, B + 5 = G, G + 5 = L, L + 5 = Q
    P + 5 = U, U + 5 = Z, Z + 5 = E, E + 5 = J
    So, the missing term is EXQJ.
    Thus, correct option is (d).
