Which of the following is required for enacting a bill into law at the federal level?

• A. It is approved by the President's cabinet.
• B. It is approved by the Supreme Court.
• C. It is approved by a two-thirds vote in both houses, but not signed.
• D. It is signed into law by the President.

Answer: (D)

When a federal bill becomes law, the final step is the President signing it. After both the House and Senate pass the bill, it goes to the President, and the President’s signature officially approves it as law. The cabinet and the Supreme Court don’t approve legislation at the federal level. There is a separate possibility: if the President vetoes the bill, Congress can override with a two-thirds vote in both chambers, and the bill becomes law without the President’s signature. But that override path is not the standard requirement to enact a bill. So the essential act to enact is the President signing the bill into law.
