The correct answer is D) a state can regulate commerce that takes place within its own borders.

The statement that best summarizes part of the ruling in Gibbons v. Ogden is "a state can regulate commerce that takes place within its own borders."

In the case Gibbons v. Ogden of 1824, Ogden filed a suit against Gibbons. The court in New York rejected Gibbon's argument saying that the Congress of the United States controlled interstate trade. The conclusion of the Supreme Court was that the states cannot interfere with the faculty that Congress has to regulate trade under the Commerce Clause.
