Answer:
"A. Congress can override a presidential veto with a two-thirds vote."
Step-by-step explanation:
The U.S. Constitution's checks and balances system is one way the government might limit the president's authority. In this system, a two-thirds majority in the House of Representatives and the Senate is required for Congress (the legislative branch) to overturn a presidential veto. This guarantees that the president cannot unilaterally veto legislation that has broad Congressional support.
Incorrect answers:
B. The Senate can vote against a treaty with a simple majority vote.
Explanation: According to Article II, Section 2 of the U.S. Constitution, ratifying a treaty needs a two-thirds majority vote (not a simple majority) in the Senate.
C. The Supreme Court, not the president, has the power to declare war.
Explanation: According to Article I, Section 8 of the U.S. Constitution, Congress (the legislative branch), not the Supreme Court (the judicial branch) or the president (the executive branch), has the authority to declare war.
D. The Supreme Court can impeach the president and remove them from office.
Explanation: Congress, not the Supreme Court, has the authority to impeach and remove the president from office. The Senate is the only body with the authority to try impeachment cases and remove the president from office with a two-thirds majority vote if they are found guilty. The House of Representatives is the only body with the authority to impeach (bring formal accusations against) the president.
