Springfield Fire Commissioner: the vast majority of false fire alarms are prank calls made anonymously from fire alarm boxes on street corners. Since virtually everyone has access to a private telephone, these alarm boxes have outlived their usefulness. Ttherefore, we propose to remove the boxes. Removing the boxes will reduce the number of prank calls without hampering people' s ability to report a fire. Which of the following, if true, most strongly supports the claim that the proposal, if carried out, will have the announced effect?
A: The fire department traces all alarm calls made from private telephones and records where they came from.
B: A telephone call can provide the fire department with more information about the nature and size of a fire than can an alarm placed from an alarm box.
C: Maintaining the fire alarm boxes costs Springfield approximately $5 million annually.
D: On any given day, a significant percentage of the public telephones in Springfield are out of service.
