A major impediment to wide acceptance of electric vehicles even on the part of people who use their cars almost exclusively for commuting is the inability to use electric vehicles for occasional extended trips.  In an attempt to make purchasing electric vehicles more attractive to commuters, one electric vehicle producer is planning to offer customers three days free rental of a conventional car for every 1,000 miles that they drive their electric vehicle.

Which of the following, if true, most threatens the plan's prospects for success?

(A) Many electric vehicles that are used for commercial purposes are not needed for extended trips.
(B) Because a majority of commuters drive at least 100 miles a week, the cost to the producer of making good the offer would add considerably to the already high price of electric vehicles.
(C) The relatively long time it takes to recharge the battery of an electric vehicle can easily be fitted into the regular patterns of car use characteristic of commuters.
(D) Although electric vehicles are essentially emission-free in actual use, generating the electricity necessary for charging an electric vehicle's battery can burden the environment.
(E) Some family vehicles are used primarily not for commuting but for making short local trips, such as to do errands.

看到答案后隐隐觉得B是对的，但是说不出所以然来。
求NN解答~

文中写得是一个计划为了吸引客人，所以只要买电动车额人每开车1000里，他们就免费送这些人3天传统车的出粗。

问，哪个能削弱计划（其实就是不吸引客人）
1:许多被用作商业用途的电动车不必被用作长途旅行 （ 商业车的用途，且是不必，并没有说不能，不能任何削弱电动车的优势，所以没有说出电动车的劣势，依然计划

2：因为很多乘客最多每周只开100里，所以生产商会增加原本已经很高的成本在电动车上 （成本很高，那么再怎么送免费的出粗期，没有用）其实说补充了一个很大的劣势
