Which of the following is a part of the federal government?

The federal government of the United States is divided into three branches: the legislative, the executive, and the judicial. Congress is the legislative branch and is responsible for making laws. It is comprised of two houses: the House of Representatives and the Senate. As a crucial part of the federal government, Congress oversees the federal budget, declares war, regulates commerce, and has the authority to check and balance the powers of the other branches.

The Supreme Court, while also a key component of the federal government, represents the judicial branch rather than the legislative branch, which is the primary function of Congress. The State Assembly operates at the state level and is part of state government, which is separate from the federal government. Similarly, the City Council pertains to local government. Therefore, Congress is the correct answer as it is a fundamental part of the federal government structure.
