How many members are in the House of Representatives?

The House of Representatives is composed of 435 members, a structure established by the United States Constitution. Each member represents a specific congressional district, and the total number of districts is set at 435. This number was determined through legislation and is intended to ensure proportional representation based on the population of the states.

The other options do not reflect the accurate composition of the House; for instance, 100 represents the total number of senators in the Senate, while 200 or 150 do not align with the established structure of either chamber of Congress. Understanding the composition of Congress is essential for grasping the legislative process and the organization of the federal government.
