The correct answer is C. The House of Representatives.

Explanation: Article I of the U.S. Constitution establishes the legislative branch of the government, which is responsible for making laws and creating policies. This branch consists of two houses: the House of Representatives and the Senate. While the Senate also plays a crucial role in policy-making, the House of Representatives is often seen as the body that directly represents the interests of the citizens, as its members are elected based on population from various states.
