Answer:
B. A common market is more deeply integrated than an economic union.
Step-by-step explanation:
An economic union is seen as a part of the different kinds of existing trade blocks. It consists of an understanding between different nations that make it possible for goods, services, and more to move from one country to the other without restrictions. The idea of an economic union is to remove internal obstructions and open to other nations to achieve free trading of resources. It is more integrated than a common market.
