    Answer : Option D

    Explanation :

    An operation with only one operand is called unary operation.
    Unary operators:
    ! Logical NOT operator.
    ~ bitwise NOT operator.
    sizeof Size-of operator.

    && Logical AND is a logical operator.

    Therefore, 1, 2, 3 are unary operators.
