Answer:

17,19

Step-by-step explanation:

twin prime numbers are those prime numbers that differ by 2.

in the options given here first one, 4 is not prime therefore the first option cannot be considered

In second option 9 is also not prime therefore is also not used.

17 and 19 both are prime numbers and differ by 2 the so it can be considered.

Moving onto the fourth one 21 and 23.Again 21 here is not prime

therefore the third option that is 17 and 19 is the correct.
