It’s B.
I’ve done this question before I remember
The first principal of Mercantilism was that all the money and wealth in the world were relatively static. The second principal of Mercantilism was that a country's wealth could be based on their fossil fuels, and resources. The third principal of Mercantilism was the striving belief that exports needed to be higher than imports.
I would assume the answer would be limited or restricted.
