Critical Reasoning

As a direct result, the cost of those products to the buyers, several export-dependent industries in Z, went up, sharply limiting the ability of those industries to compete effectively in their export markets.

Which of the following can be most properly inferred from the passage about the products whose importation was banned?

A. Those products had been cheaper to import than they were to make within country Zs fledgling industries.

B. Those products were ones that country Z was hoping to export in its turn, once the fledgling industries matured.

C. Those products used to be imported from just those countries to which country Zs exports went.

D. Those products had become more and more expensive to import, which resulted in aforeign trade deficit just before the ban.

E. Those products used to be imported in very small quantities, but they were essential tocountry Zs economy
