Solution

The correct option is C $(4, 18), (9, 38), (11, 46)$
Here, we see the first condition is that $x$ should have the value more than $3$ .
and in option $(a)$ , all values of $x$ are less than $3$ , so this option is NOT correct
Now let us check for other options
In option $(b)$
When $x = 7$ , $y = 4 (7) + 2 = 30$
$x = 5$ , $y = 4 (5) + 2 = 22$
And, $x = 13$ , $y = 4 (13) + 2 = 54$
Now, in option $(c)$
When $x = 4$ , $y = 4 (4) + 2 = 18$
$x = 9$ , $y = 4 (9) + 2 = 38$
And, $x = 11$ , $y = 4 (11) + 2 = 46$
Hence option $(b)$ and $(c)$ are correct
