What is the name of the lower house of Parliament?

The correct answer is the House of Commons, which serves as the lower house of the Parliament in the United Kingdom. In this structure, the House of Commons is directly involved in the legislative process, where Members of Parliament (MPs) are elected to represent constituencies. This house plays a crucial role in creating and passing laws, and it holds significant power over financial matters, making it a key component in the governance of the country.

The Parliament also includes the House of Lords, which acts as the upper house, but it does not have the same legislative powers as the House of Commons. The House of Representatives and the Senate, while relevant in the American legislative context, are not applicable to the structure of the British Parliament. Thus, the House of Commons is specifically recognized as the lower house due to its direct composition of elected officials and its pivotal role in democratic governance in the UK.
