(单选题)

A.To save customers time

B.To show they are high quality foods

参考答案：C

参考解析：

细节理解题。根据第二段第三句“They know that customers who buy the healthy food first will feel happy so that they will buy more junk food (垃圾食品) later in their trip”可知，商店把水果蔬菜放到前面是为了让顾客因买到健康食品而感到高兴，从而在接下来逛商店的过程中购买更多的垃圾食品。因此会发现C项更合适。A项为了节省顾客的时间，故排除。B项为了向他们展示质量较高的事物，排除。D项表达的是以一个折扣价向他们出售。故本题正确答案选C项。
