Answer 1

$13,17,19, 23$ all are prime numbers

$13^{th}$ alphabet $M$
$17^{th}$ alphabet $Q$
$19^{th}$ alphabet $S$
$23^{th}$ alphabet $W$

Answer C. $23W$

Answer 2

23W is the answer

Answer 3

in the given series the numbers are the prime numbers $13,17,19,23...$

$13 \xrightarrow{+4}17\xrightarrow{+2}19\xrightarrow{+4}23$

similarly

$M\xrightarrow{+4}Q\xrightarrow{+2}S\xrightarrow{+4}W$

So $23W$, Option $(C)$ is correct.
