The logic followed here is : All the numbers are prime numbers.

So,

3 → Prime number

5 → Prime number

7 → Prime number

9 → Not prime number ⇒ (Factors of 9 are 1, 3 and 9)

11 → Prime number

13 → Prime number

17 → Prime number

19 → Prime number

Thus, "9" is different from the rest.

Hence, "Option - (2)" is the correct answer.
