Answer:
b. to strengthen Europe's economies and unite its people
Step-by-step explanation:
The purpose of the European Union (EU) is to promote economic and political cooperation among its member countries and to improve the lives of its citizens. The EU works to achieve this by promoting trade, economic development, and political unity among its member countries. It also aims to promote peace and stability in Europe, and to foster cooperation on issues such as climate change, security, and human rights. The EU does not have the purpose of excluding Eastern European countries, finding jobs for workers from poorer countries, or decreasing governmental control of private farms.
