Which of the following is a branch or part of the U.S. government?

The U.S. government is structured into three distinct branches: the Legislative Branch, the Executive Branch, and the Judicial Branch. Each branch has its own responsibilities and functions, ensuring a system of checks and balances.

The Legislative Branch, which includes the Senate and the House of Representatives, is responsible for making laws. The Senate specifically plays a critical role in this process, as it represents the interests of the states and works alongside the House to pass legislation.

The Judicial Branch, consisting of the courts, is responsible for interpreting laws and ensuring justice is served. This branch includes various levels of courts, from local courts to the Supreme Court, which ultimately decides on key legal questions and issues.

Since all parts mentioned — the Senate, the broader Legislative Branch, and the courts — are integral components of the U.S. government, the correct answer encompasses all these branches. This comprehensive understanding reinforces the importance of each segment in maintaining the framework of U.S. governance.
