Which of the following is NOT a major power of the Executive branch?

The choice indicating that reviewing lower court decisions is not a major power of the Executive branch is accurate because this function is principally the responsibility of the Judicial branch. The Executive branch, led by the President, is primarily tasked with enforcing laws, conducting foreign policy, proposing legislation, and making treaties, all of which reflect its role in governance and international relations.

Judicial review, the process of reviewing decisions made by lower courts, is specifically within the purview of the courts and falls under the Judicial branch. The Supreme Court and other courts assess the legality and constitutionality of lower court decisions, rather than the Executive branch possessing such authority. This distinction helps clarify the separate powers and responsibilities established by the U.S. Constitution for each branch of government.
