The responsibility for making laws in the UK lies with Parliament. Parliament is the supreme legislative body that consists of two houses: the House of Commons and the House of Lords. Members of Parliament (MPs) in the House of Commons are elected by the public, while the House of Lords is made up of appointed members, including life peers, bishops, and hereditary peers.

In this legislative process, proposed laws, known as bills, are debated, amended, and voted on within Parliament. Once both houses agree on a bill, it is then sent to the monarch for royal assent, which is a formality that concludes the legislative process and allows the bill to become law. While the Prime Minister plays a significant role in shaping legislation and influencing Parliament, it is ultimately Parliament that has the authority to create laws.

The monarchy's role is mostly ceremonial, and the judiciary interprets and applies the law rather than creating it. Thus, the correct answer highlights the vital role of Parliament in the UK's legal system.
