A Correct answer
Explanation

Since this series is moving with the addition of sum of digits of previous term with the next term, that means

13 = 11 + (1 + 1), 17 = 13 + (1 + 3), 25 = 17 + (1 + 7) and so on.

24 is 1 less than the original number, so it does not follow the given pattern, therefore it is odd from all four numbers.
