Critical Reasoning

A car wash service has decided to discontinue its repeat customer coupons wherein customers who purchase 5 car washes get a 6th car wash for free. This is a smart move for the car wash service, because it must pay its workers for every car washed. Because the coupons forced the car wash service to give away numerous free car washes, the repeat customer coupons caused the company's profits to decline.

Which of the following is a reason the argument is most vulnerable to criticism?

(A) The argument ignores the fact that another customer coupon initiative could take the place of this one.

(B) The author neglects to take into account whether the profit earned by the company during the coupons initiative was greater than its costs.

(C) The argument mistakenly believes the operating costs of the car wash service can be adjusted by removing the coupon program.

(D) The author fails to consider the fact that the car wash service may be exaggerating the number of free car washes it was forced to give out.

(E) The argument overlooks potential rewards from the customer coupons initiative while focusing only on its costs.
