When summarizing a passage it is useful to scan it in order to study the structure of the text, which usually contains the main point/message.
The first sentence in the passage introduces us to alternative fuels and their benefits. The passage then goes on to describe the shortcomings of these fuels and concludes with some recommendations that will encourage the use of these fuels.
Distracters A and D offer some important facts that were detailed in the passage but are not the main issue dealt with in the passage, as we can see from its structure.
Distracters B and C both seem to deal with the central issues presented in the passage. However, upon closer examination of distracter B, it is clear that this distracter goes beyond just summarizing the passage and actually offers a piece of information that is not evident in the passage itself (by determining that alternative fuels are "the best solution").
Therefore, we are left with distracter C, which encompasses one of the main points of the passage - the popularity of alternative fuels is contingent upon the provision of a suitable infrastructure.
