Answer:
A). "You appear to be mistaken about me."
C). "I wish to set you right." "I understand your situation and can pity you."
Step-by-step explanation:
The above details most aptly back the central idea of the given passage i.e. Sindbad is clarifying that he is not that kind of person as he's thought to be. The phrase 'you appear to be mistaken about me' reveals that Sindbad does not agree with the opinion about him while the phrase 'I wish to set you right, I understand your situation and can pity you' discloses that he understands the listener's condition and willing to clarify his point that he was not blaming him at all. He explains that he has suffered a lot to reach the present happy state. Thus, options A and C are the correct answers.
