The argument above presupposes which of the following?
(A) Companies cannot find legal ways to produce technology similar to patented technology.
(B) Companies have an obligation to act in the best interest of the consumer.
(C) Too many patents are granted to companies that are unwilling to share them.
(D) The consumer can tell the difference between patented technology and inferior imitations.
(E) Consumers care more about price than about quality.
