Critical Reasoning

"In certain congested urban areas, commuters who use public transportation options such as trains and subways spend approximately 25 percent less time in transit, on average, to reach their destinations than commuters who opt instead to take cars to their destinations. Even individuals who drive their entire commute in carpool lanes, which are typically the least congested sections of roadways, still spend more time, on average, than commuters who use trains and subways."

The statements above, if true, best support which of the following assertions about commuting in the congested urban areas mentioned above?

(A) Waiting in traffic accounts for approximately 25 percent of the commuting time for individuals who drive to their destinations.
(B) Walking between a subway or train station and one's final destination does not, on average, take longer than walking between one's car and one's final destination.
(C) Using carpool lanes does not, on average, reduce driving time by more than 25 percent.
(D) Individuals who commute via public buses spend approximately 25 percent more time in transit than those who commute using public trains or subways.
(E) Subways and trains are available in the majority of congested urban areas.

OA is C
