The correct option is A
$120 - 4 x - (4 x + 10)$

Given, Jackie has 120 comic books in his shop.

If the first customer to the shop buys $4 x$ number of comic books, then the number of comic books now left with Jackie in his shop is ' $120 - 4 x$ '.

If the second customer to the shop buys two more comic books than what the first customer has bought, then it means that the second customer has bought $4 x + 10$ comic books.

Hence the number of comic books left with Jackie in his shop is ' $120 - 4 x - (4 x + 10)$ '.
