Saw this on a MGMAT CAT - correct answer is apparently (A) but I think there are definitely merits to (C). Any thoughts?
Many banks offer drive-through automatic teller machines (ATMs), which are located on the driver’s side of a lane accessible only to automobiles; pedestrians and cyclists are not allowed to enter the lanes. Clearly, blind people do not drive automobiles; nevertheless, like the universally accessible ATMs inside the bank branches, all of the drive-through ATMs have both Braille and visible numbers on their keypads.
Which of the following, if true, most helps to explain the discrepancy described in the passage?
A) The cost per unit to ATM manufacturers of producing multiple types of ATMs is substantially greater than that of producing one universal model.
B) Both the drive-through ATMs and the universally accessible in-branch ATMs feature multiple languages in their audio and video output.
C) Federal regulations require that all ATMs accessible to the blind must have keypads featuring both Braille and visible numbers.
D) The blind make up a higher percentage of the banks’ customers than they did in previous decades.
E) Recent advertising campaigns at the banks in question have focused on reaching out to disabled customers.
