Choice B is the best answer. In (lines 35-37"It...Shanghai"), the author provides evidence that some public transportation systems are superior to driving, because public transportation "can be faster, more comfortable, and cheaper than the private automobile."
Choices A, C, and D do not provide the best evidence that some public transportation systems are superior to driving, as they highlight points made in the fourth paragraph rather than the paragraph's central idea.
