    B KXBQEW Correct Answer Incorrect Answer
    C KXBWQE Correct Answer Incorrect Answer
    D KXQEBW Correct Answer Incorrect Answer

    Solution

    The logic followed here is that the first and last letter of the word is replaced by 5th succeeding letter and all the middle letters of the word are replaced by 3rd preceding letter as per English alphabetical series.

    In LIGHT,

    L + 5 = Q, I – 3 = F, G – 3 = D, H – 3 = E, T + 5 = Y

    Code for LIGHT is QFDEY

    Similarly,

    In PLUM,

    P + 5 = U, L – 3 = I, U – 3 = R, M + 5 = R
    Code for PLUM is UIRR

    Similarly,

    In FATHER,

    F + 5 = K, A – 3 = X, T – 3 = Q, H – 3 = E, E – 3 = B, R + 5 = W

    Code for FATHER is KXQEBW
