1. 41
2. 16
3. 281
4. 230

Answer 1

Correct Answer - Option 1 : 41

The logic is as follows:

243 → This number is multiple of 3.

280 → This number is multiple of 7, 5 and 2.

172 → This number is multiple of 2.

230 → This number is multiple of 2, 5 and 23.

92  → This number is multiple of 2 and 23.

41  → This number is a prime number.

14  → This number is multiple of 2 and 7.

Hence, 41 is the odd one out.
