What mystery does Rahim Khan reveal in the final pages?

• A. They are secretly cousins.
• B. They are half-brothers, with Baba as Hassan's father.
• C. They are not related at all.
• D. They are father and son.

Answer: (B)

The question tests how a hidden family secret changes how we understand the characters’ past and motives. The big reveal Rahim Khan shares is that Hassan is Baba’s son, making Amir and Hassan half-brothers. In other words, Baba is Hassan’s father, which reframes their whole relationship and explains the strange mix of love, loyalty, and social tension surrounding Hassan. This truth adds weight to Amir’s guilt and heightens the themes of redemption and forgiveness, since Amir begins to see Hassan not just as a loyal friend but as a family member whose fate is bound to his own.
