How does a veto work?

• A. The President Can Sign a Bill Into Law and Congress Overrides With a Two-Thirds Vote
• B. The President Can Sign a Bill Into Law Without Any Congressional Action
• C. Only the Supreme Court Can Veto a Bill After It Becomes Law
• D. The President Can Veto a Bill; Congress Can Override With a Two-Thirds Vote in Both Houses

Answer: (D)

The test is about how the President’s veto and Congress’s ability to override it create a check and balance in lawmaking. A veto happens when the President refuses to sign a bill and sends it back to Congress with a explanation. Congress can still make the bill a law if both the House and the Senate vote again to pass it by a two-thirds margin. If they achieve that two-thirds in both chambers, the bill becomes law without the President’s signature. If they can’t reach that level of support, the veto stands and the bill dies.

That’s why the correct understanding is that the President can veto a bill, and Congress can override with a two-thirds vote in both houses. The other ideas don’t fit: a bill can’t become law with zero congressional action, the Supreme Court doesn’t veto bills (it can strike them down after passage), and you can’t override a veto after a bill has already been signed into law.
