Bicameralism and presentation require that a bill

• A. Be approved by both houses and signed by the President.
• B. Bypass the President and become law after approval by a single house.
• C. Be declared unconstitutional by Congress before becoming law.
• D. Pass both houses and be presented to the President for signature or veto.

Answer: (D)

Bicameralism and presentation mean a bill must go through both chambers and then be presented to the President for signature or veto. This ensures both houses participate and the executive can review the measure. Once both houses pass the same version, the bill is sent to the President, who can sign it into law or veto it. If vetoed, Congress can override with a two-thirds vote in each house, making it law without the President’s signature. A bill cannot become law after only one house’s approval, and Congress does not declare laws constitutional; that power lies with the courts. So the necessary path is for a bill to pass both houses and be presented to the President for signature or veto.
