A. Currently, Stellar Inc. is the industry leader.
We cannot be sure of this. May be Stellar Inc. is trying to be industry leader.
B. A company that is not an industry leader cannot foster industry innovations unless it stops following other companies.
A company that is not an industry leader can foster industry innovations and can follow the other companies.
C. If a company does not identify an industry innovation that will turn out to be the next big rage in the industry, that company cannot become the industry leader.
Argument states that next new rage but this answer choice talks about the next big rage. Thus we move from this answer choice.
D. Stellar Inc. will not achieve its goal unless it can identify an industry innovation that will turn out to be the next new rage in the industry.
This can be inferred from the argument.
E. Companies that are focused on and satisfied with existing standards and are merely following other companies will become industry leaders only if they emulate Stellar Inc.
This cannot be true as these companies will not become industrial leaders.
Choice C talks about the next big thing and Choice D talks about the next new thing. Argument talks about the next new things, thus choice D is correct answer
