Question

who has the power to appoint a body capable of invoking the 25th amendment? the supreme court the secretary of state congress

Explanation:

The 25th Amendment outlines procedures for presidential succession and disability. While the amendment itself does not require appointing a separate body to invoke it, Congress has the authority to legislate on related processes if needed, and among the options, it is the only entity with constitutional power over such structural or procedural matters related to government operations. The Supreme Court interprets laws, and the Secretary of State is an executive branch official with no role in appointing bodies for 25th Amendment invocation.

Answer:

Congress
