GMAT Critical Reasoning (CR) | Re: Two computer companies, Garnet and Renco, each pay Salcor to

A,D,E are out of scope because these options discuss something else that are not covered in the argument, and also, all of these questions do not relate to both companies.
B does not address the issue in the argument, then it is C even though C is quite confusing, and difficult to understand.
