Correct Answer:
C. Belgium
Belgium, specifically its capital Brussels, is the customary host for the majority of major European Union leaders' summits, including the regular meetings of the European Council. Brussels serves as the de facto capital of the EU, housing the main institutions such as the European Commission, the Council of the European Union, and the European Parliament. This central location ensures continuity and accessibility for all member states.
- The UK is no longer a member of the European Union, so it would not host an EU leaders' summit.
- France and Finland are EU member states, and while they might host specific ministerial meetings or informal summits during their rotating presidencies, the primary and regular European leaders' summits are consistently held in Brussels.
