The pattern of reasoning in the argument above is most closely paralleled in which one of the following

A.It would be more convenient for Deminique to take a bus to School than to take the subway, since the bus stops closer to her house than does the subway and, unlike the subway, the bus goes directly to the school.

B.Joshua’s interest would be better served by taking the bus to get to his parent’s house rather than by taking an airplane, since his primary concern is to travel as cheaply as possible and taking the bus is less expensive than going by airplane.

C.Belinda will get to the concert more quickly by subway than by taxi, since the concert takes place on a Friday evening and on Friday evenings traffic near the concert hall is exceptionally heavy.
