FastMart, a convenience store chain, is planning to add pancake syrup to the items it sells.  FastMart stores do not have shelf space to stock more than one variety of syrup.  Surveys of FastMart customers indicate that one-fourth of them prefer low-calorie syrup, while three-fourths prefer regular syrup.  Since FastMart’s highest priority is to maximize sales, the obvious strategy for it is to stock regular syrup.

Which of the following, if true, most seriously weakens the argument?

A.    eople buying pancake syrup at convenience stores, unlike those buying it at supermarkets, generally buy it only a few times.
B.    eople who prefer low-calorie syrup generally use about the same amount of syrup on their pancakes as those who prefer regular syrup.
C.    Regular syrup does not sell for a higher price per unit than low-calorie syrup.
D.    In general, customers who prefer regular syrup will buy low-calorie syrup if regular is unavailable, but those who prefer low-calorie will not buy regular syrup.
E.    Sales of syrup are not expected to account for a large proportion of total dollar sales at the average FastMart store.

本来这题的c和d选项我觉得都可以，也都有问题
c只说not higher，没有说明的low-calorie syrup价格足以弥补1／4的总量。
d的说法也没有明确的价格说明。
后来 我看到问题是FastMart’s highest priority is to maximize sales
我想问下这题的原因是不是因为这个sales？指销量而不是利润？

是SALES
