What is the name of the second-largest party in the House of Commons?

Okay, let's break down the party system in the UK Parliament to understand why "the opposition" is the correct answer. In the UK, we have a multi-party system, but it's usually dominated by two major parties. The party that wins the most seats in a general election forms the government. Now, the party with the *second* largest number of seats doesn't just disappear; they become the official opposition. Their main job is to scrutinize the government's policies and actions, offering alternative viewpoints and holding them accountable. Think of them as the government-in-waiting, ready to step in if the government loses a vote of no confidence or the next election. The term "the cabinet" refers to the group of senior ministers chosen by the Prime Minister to lead different government departments, and "the country party" isn't a recognized term in UK politics. So, the opposition is the correct answer because it accurately describes the role of the second-largest party in the House of Commons.
