A product that represents a clear technological advance over competing products can generally command a high price. Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the maximum possible price for such a product.But large profits on the new product will give competitors a strong incentive to quickly match the new product's capabilities.Consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price.

In the argument above, the two portions in boldface play which of the following roles?

(A) The first is a consideration that has been raised to argue that a certain strategy is counterproductive; the second presents that strategy.

(B) The first is a consideration raised to support the strategy that the argument recommends; the second presents that strategy.

(C) The first is a consideration raised to explain the appeal of a certain strategy; the second presents that strategy.

(D) The first is an assumption, rejected by the argument, that has been used to justify a course of action; the second presents that course of action.

(E) The first is a consideration that has been used to justify pursuing a goal that the argument rejects; the second presents a course of action that has been adopted in pursuit of that goal.

答案：C

灰常灰常灰常不能理解，第一个黑体字支持的a certain strategy因该是：many companies charge the maximum possible price for such a product.  而第二个黑体字的strategy又不同。为什么选C啊。
不过除了以外我觉得其他的也不对，这题纠结了很久，其实我觉得没答案。各位怎么看？
