Who signs bills to become laws?

The President is responsible for signing bills into law, which is a critical part of the legislative process in the United States. Once Congress has drafted and approved a bill, it is sent to the President. The President has several options: they can sign the bill into law, veto it (reject it and send it back to Congress), or take no action, which could result in the bill becoming law after a certain period (if Congress is in session) or being pocket-vetoed (if Congress adjourns before the period expires).

This process highlights the checks and balances inherent in the U.S. government, where the legislative branch (Congress) and the executive branch (the President) must work together to enact laws. While the Vice President plays a role in the Senate, primarily to cast deciding votes when there is a tie, they do not have the authority to sign bills into law. The Supreme Court's role involves interpreting laws and ensuring they comply with the Constitution, rather than participating in the legislative process. Thus, the President is indeed the correct choice for this question.
