Question

Which of the following countries has the headquarters of the European Union?
a. USA
b. France
c. Belgium
d. Australia

Answer 1

Hint:
The European Union is a federal and economic body composed of 27 member countries, initially based in Europe. Via a controlled arrangement of codes that relate to certain matters in all member countries and only those concerns where countries agreed to operate as one, the EU has established an enclosed individual market.

Complete solution:
The EU has formed an internal customs union by means of a consistent method of legislation that applies to these matters in all Member States, except only in those situations where the members have agreed to function as one. The objective of EU policies is to ensure the free flow of citizens, goods, services, and resources within the internal market; enforce justice and home affairs laws; and sustain common exchange, agriculture, fisheries, and rural development policies.
Its members have a combined area of 1,634,469.0 sq. mi (4,233,255.3 km2) and an overall estimated population of approximately 447 million. When the Maastricht Treaty came into force in 1993, the EU and European citizenship were developed. Now, having its headquarters in Brussels, Belgium, the de facto capital.
The Treaty of Paris, which formed the European Coal and Steel Group (ECSC), was established in 1951 by the representatives of six European countries (Belgium, Luxembourg, the Netherlands, France, Italy, and West Germany), bringing with them and the first institutions: The High Power, the cabinet of state, the Court of Justice and the Common Legislature.
By the entry of new Member States, the Organizations and their successors have grown in size and in power by introducing policy areas to their agenda. The new big amendment to the EU's constitutional foundation, the Lisbon Treaty, came into force in 2009.
Hence, the correct answer is option C.

Note:
The EU hasn't had an official capital and has no intention to declare one, but Brussels is home to the official seats of the EU parliament, the Council of the European Union Council, as well as the centre of the European Parliament (which would be formally the second but de facto the most significant seat).
