Which of the following most logically completes the argument?
For the past fifteen years, tower-based satellites have been used to transmit voice communications between air traffic controllers and pilots. Over the past year, two aviation technology firms, Rion and Hirsk, have each come out with ground-based devices that allow voice communications between air traffic controllers and pilots to occur at five times the speed and with five times more clarity than the current satellites allow. Although the devices are similar in price and equally reliable, Rion's device is likely to be more successful, because ________.
(A) Hirsk has been developing air-to-ground communication systems for a longer period of time than Rion has
(B) the number of airports that require ground-based communication devices is likely to triple over the next several years
(C) it is much more likely that Hirsk's system will be expandable to serve airports as they become more congested in the future
(D) unlike many aviation firms, Rion and Hirsk develop aircraft engines in addition to air-to-ground communication systems
(E) it is easier for airports that use the current satellite technology to switch to Rion's ground-based device than to Hirsk's
