Which branch of government is primarily responsible for making federal laws?

The Legislative Branch is primarily responsible for making federal laws, as it is the branch of government that is specifically tasked with creating, debating, and passing legislation. This branch is composed of two chambers: the House of Representatives and the Senate. Members of the Legislative Branch are elected officials who represent the interests of the citizens and the states they serve. They propose bills, engage in discussions regarding the nation's policies, and must work together to ensure that laws reflect the will of the people.

The Executive Branch, while it does enforce laws and has a significant role in setting policy through initiatives and veto powers, does not have the authority to create laws itself. Similarly, the Judicial Branch is focused on interpreting laws and ensuring justice, not making them. Regarding the Administrative Branch, this term is often used informally to describe the various departments that operate under the Executive Branch but does not represent a distinct branch of government in the constitutional framework. Thus, the distinct function of the Legislative Branch in law-making is what makes it the correct answer.
