Critical Reasoning (CR) | According to results from brain scans, the insulaa brain area

According to results from brain scans, the insula―a brain area associated in part with pain-exhibits heightened activity when consumers think about how much a purchase will cost. In a recent study, researchers auctioned off tickets to a sold-out event. Half the study participants were to use cash to buy the tickets, while the other half were to pay by credit card. The credit card buyers bid, on average, twice as much as the cash buyers bid. This shows that credit cards, because they involve paying later, limit consumers' thoughts about price: credit card users are willing to spend more money because they experience lesspain.

So, the argument works even if this choice is not true.

Honestly, I don't really like this incorrect choice because I could see it being considered correct in a CRquestion , but since there are clear reasons to choose (C) over this choice, the question isgettable.
