A client, who has recently sought out therapy for marital stress due to his wife finding out that he had been having an extramarital affair, enters the office with his wife. He had not told you previously that he would include her in sessions. He asks to have her join the session. She starts the session by asking you what your client has told you about him still seeing the other woman. Which of the following accurately states the ethical guide in this matter?

a. Answer her that he said he had not been seeing her for some time because this is true. The client just gave you permission to answer, and it will help them continue to heal. 

b. Refuse to answer the question and ask the client's wife to leave. 

c. Answer the question only after checking with your client whether he would like you to answer. He had been telling you he hadn't been seeing her. 

d. Refuse to answer the question, explain why, and process trust issues between them.
