Answer:

The correct answer is option 'A', Britain.

Explanation:

In June 2016, the United Kingdom (UK) voted to break away from the European Union (EU) in a referendum. This historic event came to be known as Brexit, which is a portmanteau of the words "Britain" and "exit." The decision to leave the EU was made by a very narrow margin, with 51.9% of voters choosing to leave and 48.1% voting to remain.

Here is a detailed explanation of Brexit:

1. Background:
- The UK joined the European Economic Community (EEC), which later became the EU, in 1973.
- Over the years, the EU expanded its influence and powers, leading to debates and concerns within the UK about sovereignty and control over its own laws, borders, and economy.
- In response to these concerns, then-Prime Minister David Cameron promised to hold a referendum on EU membership if his Conservative Party won the 2015 general election.

2. The Referendum:
- On June 23, 2016, the UK held a referendum to determine whether it should remain in the EU or leave.
- The question posed to voters was: "Should the United Kingdom remain a member of the European Union or leave the European Union?"
- The majority of voters chose to leave, triggering the process of withdrawing from the EU.

3. Negotiations and Withdrawal Process:
- Following the referendum, the UK government invoked Article 50 of the Treaty on European Union, officially beginning the withdrawal process.
- Negotiations between the UK and the EU took place to determine the terms of the withdrawal agreement, including issues such as trade, immigration, and the rights of EU citizens in the UK and vice versa.
- After several years of negotiations, the UK formally left the EU on January 31, 2020, entering a transition period until December 31, 2020.

4. Implications and Future Relations:
- Brexit has had significant implications for both the UK and the EU.
- The UK has regained control over areas such as immigration, trade policy, and agricultural subsidies.
- However, it has also faced challenges, including economic uncertainties, trade disruptions, and the need to establish new agreements with the EU and other countries.
- The long-term future relationship between the UK and the EU is still being negotiated, with ongoing discussions on issues such as trade, security, and cooperation.

In conclusion, Britain voted to break away from the European Union by a very narrow margin in June 2016, and this breakaway became known as Brexit.
