Can we draw the following hypothesis from the context (see options)? 

Context:

The Government has argued as if petitioners had advanced a general theory of the Copyright Clause, or a general constraint under which Congress must operate. That is a mistake. This case is about limits to an enumerated power. It's not about general power of Congress to exercise its copyright authority.

Hypothesis: Copyright Clause contains a q
OPT:
a). Yes;
b). It's impossible to say;
c). No;
