Kim: Some people claim that the battery-powered electric car represents a potential solution to the problem of air pollution. But they forget that it takes electricity to recharge batteries and that most of our electricity is generated by burning polluting fossil fuels. Increasing the number of electric cars on the road would require building more generating facilities since current facilities are operating at maximum capacity. So even if all of the gasoline-powered cars on the roads today were replaced by electric cars, it would at best be an exchange of one source of fossil-fuel pollution for another.
The main point made in Kim’s argument is that
(A) replacing gasoline-powered cars with battery-powered electric cars will require building more generating facilities
(B) a significant reduction in air pollution cannot be achieved unless people drive less
(C) all forms of automobile transportation are equally harmful to the environment in terms of the air pollution they produce
(D) battery-powered electric cars are not a viable solution to the air-pollution problem
(E) gasoline-powered cars will probably remain a common means of transportation for the foreseeable future

This passaage argues that electrical vhecle can solve the problem of air pollution. As author says e-vhecle making will just change the application in which the fuels are burned.
Answer D supports this reasoning.

A is too specific and talks only about one part of the argument.
B is out bc we dont know whether driving less can reduce air pollution.
Future predictions are not part of the argument So, E is out.
In case of C, we dont know if "all forms of automobile" are equally harmful, comparison is only bw electric and gasoline-powered cars.
That leaves us D, which is the closest to main point.
