    Answer: (4) 1234

    Explanation:-
    Divisibility of 3
    If the sum of the digits of the number is divisible by 3 that number will be divisible by 3.

    Then, taken option 1,
    The sum of the digits of 123 = 1 + 2 + 3 = 6 , 6 is divisible by 3, then the will divided by 3.

    Taken, Option 2,
    The sum of the digits of 123456 = 1 + 2 + 3 + 4 + 5 + 6 = 21, 21 is divisible by 3, then edupilthe number will be divisible by 3.

    Taken option 3,
    The sum of the digits of 12345 = 1 + 2 + 3 + 4 + 5 = 15, 15 is divisible by 3, then the number will be divided by 3.

    Taken, option 4,
    The sum of the digits of 1234 = 1 + 2 + 3 + 4 = 10, 10 is not divisible by 3, then the number will not be divisible by 3

    Then, 1234 is not divisible by 3.

    Hence, the answer is (4) 1234.
