There is only one major road, Freeway Z, that links County X and County Y. The border of the two counties is primarily defined by a mountain range, over which the construction of new roads is severely restricted by environmental laws. A cost-effective solution to the problem of traffic congestion on Freeway Z is to build a commuter train tunnel through the mountain range. The successful implementation of this plan would cost far less than expanding the existing freeway and would also reduce the number of cars clogging the roads in both counties.

Which of the following, if true, could proponents of the plan above most appropriately cite as a piece of evidence for the soundness of their plan?

A. An effective commuter train tunnel between the counties would require major investment in mass transit within both counties.
B. The majority of all vehicles on the nation's freeways are traveling from one state to another.
C. 60% of the cars on Freeway Z are driven by people who live in County Y and work in County X.
D. Many new freeways are being built in areas that are presently served by commuter trains.
E. A large proportion of the vehicles on Freeway Z are commercial trucks carrying transcontinental shipments.


What's the best approach to determine the answer?

What is the OA here? I think that E is not correct.
