What did the U.S. Supreme Court decide in the case of the United States v. Nixon (1974)?

This statement misrepresents the separation of powers doctrine. While Congress does have significant oversight capabilities, the Supreme Court also plays a critical role in checking the executive branch through judicial review, which includes adjudicating issues of executive privilege.

This choice is incorrect because the Supreme Court explicitly rejected the notion that executive privilege is absolute. The Court determined that the need for evidence in a criminal case outweighed the President's claim of privilege, leading to the requirement for compliance with the subpoena.

This option fails to recognize the judiciary's role in interpreting the law, including executive privilege. The Supreme Court's decision in United States v. Nixon underscored its authority to resolve disputes regarding the limits of executive privilege, thereby emphasizing its critical position within the checks and balances framework.
