Solution

The correct option is B $2$
Option $A :$ Substitute $x = 0,$
$x, x + 1, x + 3 = 0, 1, 3$ are not prime numbers.

Option $B :$ Substitute $x = 1,$
$x, x + 1, x + 3 = 1, 2, 4$ are not prime numbers.

Option $C :$ Substitute $x = 2,$
$x, x + 1, x + 3 = 2, 3, 5$ which are all prime numbers.

Hence, option $C$ is correct.
