单项选择题

A brand of cough syrup comes with a measuring cup attached so that customers can measure the proper dosage. A consultant has pointed out that this cup is unnecessary, since most customers have measuring cups at home. Since the cups increase the cost of packaging the cough syrup and reduce the total number of units that can be shipped in a standard package, the consultant advises that the company can increase its net revenue on this product (total revenue minus total costs) by selling the cough syrup without the measuring cups.
Which of the following, if true, provides the pest evidence that the company should not follow the consultant’s advice ？（）

A. Studies have shown that customers who use cough syrup without a measuring cup frequently take either too little or too much of the medicine, rendering the dosage either ineffective or, in cases of overdose, dangerous.

B. The company has included a measuring cup with each bottle of cough syrup for the last 18 years.

C. Studies have shown that 85 percent of consumers possess at home either a measuring cup, a set of measuring spoons, or both.

D. Many customers neglect to follow the recommended dosage of cough syrup even when the measuring cup is packaged along with the bottle of cough syrup.

E. Shipping the cough syrup bottles without the measuring cups will provide a marginal improvement in the number of cough syrup bottles that can be shipped in a standard package.
