(A) is wrong because it overstates the case. The mayor's personal interest is not sufficient to show that she's behaved wrongly. Still, that doesn't mean that her personal interest is irrelevant to any assessment of her action!
This is a common way to construct a bad answer; take a kernel of truth (the personal interest isn't decisive), then turn it into a statement so big it isn't even true any more (her personal interest is completely irrelevant).
