The correct answer is C.
Gibbons v. Ogden was a case solved by the US Supreme Court in 1824 and which led to the enactment of a landmark decision.
The final decision stated that the US federal powers were in charge of regulating interstate commerce, because of the Commerce Clause, included in the US Constitution and which grants such powers to the US Congress. It also includes the power of regulating navigation. Therefore, from this moment onwards, monopolies cannot be established at the state level as such actions would be contradicting the regulations fixed by the supreme federal powers.
