    Why this is right

    This survey was just asking a head to head question, "are you more concerned with A or B?" That doesn't assume that A and B are the only two things the respondent is concerned with. This answer tells us, "people are also concerned about C!" Okay, so what? That doesn't have anything to do with judging whether the survey results of a poll about "A vs. B" should be trusted or not. Since this has no impact, it's the correct answer.
