I also think the odd one out is 331 as 3 + 3 + 1 = 7 which is not equal to 11 or 14. As for all the other numbers, the sum of digits is 11 or 14.

If you add 1 to every option it becomes a multiple of 3 except for 331. Then why can't we have 331 as the answer?

3 + 3 + 1 = 7(Odd).
5 + 5 + 1 = 11(Odd).
2 + 6 + 3 = 11(Odd).
3 + 8 + 3 = 14(Even) - (Ans).
3 + 3 + 1 = 7(Odd).
5 + 5 + 1 = 11(Odd).

Why not like 3+3+1=7?

4+8+2=14,....like that, except 331 sum of each will return 2 digit value.

Then why not 331 would the answer?

3*3=9 hear for the 8. So read the sentence means odd man out because no multiply in digits so 383 is right.

The product of all 3 digits is a perfect square except the product of 3*8*3.

Like;

3 * 3 * 1 = 9
4 * 8 * 2 = 64
5 * 5 * 1 = 25
2 * 6 * 3 = 36
3 * 6 * 2 = 36
2 * 8 * 4 = 64.
But
3 * 8 * 3 = 72
