Anita, Who Is a Seamstress, Agrees to Sew a Suit

Anita, who is a seamstress, agrees to sew a suit for Bryan, who promises in return to pay Anita $500 for the suit if he is satisfied with it. Anita completes the suit, which fits Bryan perfectly. Nevertheless, he says that he is not satisfied and refuses to accept or pay for it. If Bryan is honest in his dissatisfaction, but he is unreasonable:

A) Bryan must pay for the suit even if he is dissatisfied.
B) this is an illusory contract, because only Anita is bound.
C) Bryan's approval is to be judged by an objective standard.
D) Anita has no recourse against Bryan, because she agreed to the subjective standard.
