Answer:
B. Free trade
Step-by-step explanation:
Free trade is an element of global trade that allows for growth and diversity.
Free trade is an economic policy where there are no tariffs, duties on imports and taxes. It is a Laissez faire and the government does not interfere on exports through the imposition of the duties, tariffs, quotas and taxes on what is exported.
This policy brings about lower prices for the consumers, exports would be increased and also there are more choices of goods available. This brings about growth and diversity.
