    Question

    Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster DOES NOT belong to that group?
    (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter-cluster.)

    A.

    EF

    B.

    AF

    C.

    AD

    D.

    CA

    Correct option is A

    Checking by all options:
    Logic = find adjacent in the alphabetical series.

    AI: A and I are not adjacent in the alphabet.
    EF: E and F are adjacent in the alphabet.
    AD: A and D are not adjacent in the alphabet.
    CA: C and A are not adjacent in the alphabet.

    Hence option A is correct.
