Answer:
A. Infuriated.
Step-by-step explanation:
The short story "Saboteur" by Ha Jin narrates how a University lecturer was wrongfully arrested and kept captive by the police, tortured and forced to accept responsibility to save his friend and himself from further torture. The story, set right after the cultural revolution in China.
The given excerpt is after the protagonist Mr. Chiu had been in prison for a couple days. He had advised his new wife to send someone to help, so when he saw Fenjin out in the backyard of the prison, he knew she must have sent him. He had expected "a cadre" from "the school's security section", not this lawyer who does "some detective work for men and women who suspected their spouses of having extramarital affairs". Through his expression of claiming she is "a stupid woman", we can deduce that he is infuriated with her for who she had decided to send.
