Answer:
Option C, limiting the amount of Brazilian sugar that can be imported, is the right answer.
Step-by-step explanation:
The term Import Quota is referred to a limit placed by a country on the import of any product which the country imports from a particular country.
Import quotas are enacted to reduce the import of a particular good and to aid the domestic suppliers. It may result in higher prices of commodities for consumers, a decline in economic welfare and that other countries can also place tariffs on the export from the country which placed import quota.
Accordingly, if the United States places a quota on the import of sugar from Brazil then the amount of sugar imported in the U.S. will be limited.
