Critical Reasoning

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 eclectic 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 eclectic 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.
i feel E is also a good option because if people use cars for making short local trips , then they will longer time to redeem the free rental compared to people who use cars for commuting . doesn't this threaten the plans success
