Critical Reasoning

For the past several years, a certain technology has been widely used to transmit data among networked computers. Recently two data transmission companies, Aptron and Gammatech, have each developed separate systems that allow network data transmission at rates ten times faster than the current technology allows. Although the systems are similarly priced and are equally easy to use, Aptron's product is likely to dominate the market, because _______________.

A. Gammatech has been in the business if designing data transmission systems for several years more than Aptron has
B. the number of small businesses that need computer networking systems is likely to double over the next few years
C. it is much more likely that Gammatech's system will be expandable to meet future needs
D. unlike many data transmission companies, Aptron and Gammatech develop computers in addition to data transmission systems
E. it is easier for users of the current data transmission technology to switch to Aptron's product than to Gammatech's


[spoiler]I think the answer should be E, as it gives a correct reason as to why Aptron's product will dominate Gammatech's product as users will find it easier to switch to the earlier system (Aptron's). Also this implies that Aptron's product might be similar to the current data transmission technology in use.

Please throw some light on the above.
