In the case of mcculloch v. maryland, the supreme court a. retained authority to judge the constitutionality of congressional laws b. upheld the constitutionality of the second bank of the united states c. prohibited slavery north of the ohio river d. put aside land-purchase contracts signed by native americans.

b. upheld the constitutionality of the Second Bank of the United States

Explanation:

The case McCulloch v. Maryland reached the US Supreme Court because Maryland passed a law that imposed taxes on the Second Bank of the United States, but McCulloch refused to pay the taxes, the state of Maryland appeals court decided that the Second Bank was unconstitutional because the US Constitution did not provide authorization to the federal government to charter a bank.

The US Supreme Court decided unanimously that the Congress had the power to incorporate the bank and that the State of Maryland could not tax instruments of the national government. Also, the Court ruled that Congress has more than explicit powers, it also has implicit ones.
