It's C. A and B are wrong.
Hello,
David is thinking about his quest for manhood, which he connects with
owning a gun. Because he is “almost a man,” he believes that he should
own the symbol of manhood: a gun. Borrowing a mail-order catalog from a
local store owner so that he can look at the pictures of revolvers,
David becomes obsessed with thoughts of guns, becoming a man, and, most
important, the strategy that he must use to persuade his mother that he
should be able to buy a gun. A real man doesn't need a gun.
