The correct answer is "B"
Mercantilism is an economic system that is based on the development of trade and export. His doctrines were developed between the sixteenth and eighteenth centuries in Europe.
For the establishment of mercantilism, a strong state was required that could take the necessary measures to regulate the economy. It was considered that the prosperity of each nation was linked by the capital accumulated by it, which in turn was represented by the accumulation of precious metals held by the State.
Mercantilist theorists argued that such capital could increase from a positive trade balance, that is, with a level of exports that exceeds the level of imports. This translated into a government that had to implement protectionist policies, protecting domestic production with import tariffs and favoring exports.
