Whether "belief" or "guess," the real problem here seems to be with the OBJECT of the belief/guess. Sarah's reckoning is about why Michael "told that fact," not about why Michael "donates a tenth of his income to charity." IMHO, this is the real reason why answer choice (B) is incorrect.
Put another way, answer choice (B) would be correct if it were slightly modified as follows:
"It was correct for Sarah not to praise Michael for being charitable when he told her that he donates a tenth of his income to charity, since she guessed that he only donates his income in order to impress her."
If you believe I'm wrong, or guess I'm off my rocker, please lemme know! ...and please specify which!
