Question

a quota is:
select one:
a. a patent license
b. a quantity limit on imports
c. an export ban
d. a tariff rate

Explanation:

A quota, in trade terms, refers to a government-imposed quantity restriction on imported goods. Option a is incorrect (patent license relates to intellectual property), option c is wrong (export ban is a full prohibition on exports, not a limit), and option d is a tariff (a tax on imports, not a quantity limit). Thus, option b is the correct definition.

Answer:

b. A quantity limit on imports
