Brexit refers to which of the following?

• A. The United Kingdom's withdrawal from the European Union.
• B. The creation of a new UK currency separate from the euro.
• C. A trade agreement that binds the UK to EU rules indefinitely.
• D. A domestic policy to reduce immigration.

Answer: (A)

Brexit means the United Kingdom leaving the European Union. It was a political and legal process that began after a 2016 referendum and culminated in formal withdrawal, with the aim of the UK reasserting control over its laws, borders, and trade, rather than being governed as an EU member. The other descriptions miss this core idea: one describes creating a separate currency (the UK uses the pound, not the euro), another suggests a trade pact that binds the UK to EU rules forever (Brexit moves away from that binding structure), and the last points to immigration policy alone, which is not what Brexit defines.
