3+3+1=7.
4+8+2=14.
5+5+1=11.
2+6+3=11.
3+8+3=14.
3+6+2=11.
2+8+4=14.

It can be 331 because other all number add and get answer 11 & 14. and 7 are different.

3*1=3 , 3(3)1 =331.

4*2=8 , 4(8)2 =482.

3*3=9 , 3(8)3 =383,

In each number except 383, the product of first and third digits is the middle one.

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.

Agree with above, 331 is also the only option, that when all digits are added, the answer is a single digit (meaning lower than 10).

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 + 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).

Another Option:

If we divide each number by 3 then we get remainder 2 except in 331. So option 'c' is also odd man out.

In first number 331 : 3x1=3

In 2nd number 482 : 4x2=8

But in 383, 3x3 is 9 (expected is 8). So this is odd one out.

It can be 551 as well because only in this number the sum of the extreme two digits is greater than the middle digit.

3 * 1 = 3 331.
4 * 2 = 8 482.
5 * 1 = 5 551.
2 * 3 = 6 263.
3 * 3 = 9 383 it is wrong.
3 * 2 = 6 362.
2 * 4 = 8 284.
