    Question

    Refer to the following number series and answer the question that follows (all numbers are single-digit numbers only). Counting to be done from left to right only.
    (Left) 7 4 1 2 4 9 8 5 3 6 1 5 4 6 7 4 8 3 9 6 5 2 3 9 1 4 2 (Right)
    How many such even numbers are there, each of which is immediately preceded by a perfect square and immediately followed by an odd number? (NOTE: 1 is also a perfect square.)

    A.

    Three

    B.

    One

    C.

    More than three

    D.

    Two

    Correct option is C

    Given: (Left) 7 4 1 2 4 9 8 5 3 6 1 5 4 6 7 4 8 3 9 6 5 2 3 9 1 4 2 (Right)
