In exchange for his mercy, what promise does hester prynne make chillingworth at the end of chapter 4 of the scarlet letter? a. she promises to never stray from him in their marriage again. b. she promises to bear him a child, as well. c. she promises to tell pearl that he is her father. d. she promises to keep his identity a secret. b is wrong

In my opinion, the correct answer is D. She promises to keep his identity a secret. Hester had recognized her husband when she spotted him outside, at the gallows. In Chapter 4, they are facing each other in her prison cell. Chillingworth now wants to find out the identity of Hester's secret lover, which she refuses to reveal, but also agrees that she would keep his own identity a secret.
