Answer:
The correct answer is A. Some people believe that illegal drugs bring twice as much money into Colombia as coffee does.
Explanation:
Despite Colombian military operations against drug trafficking, particularly with United States support under the Colombia Plan, Colombia is the world's leading cocaine producing country and dominates about 70% of the world's cocaine market according to Interpol, with production declining from 690 tonnes in 1999 to 440 in 2003 on a little over 100,000 hectares.
The export of cocaine to the United States is done in a variety of ways, in particular via submarines or boats, but also by air, either using small planes from Colombia to Central America (mainly to Mexico), or with human couriers (mulas) using airliners.
In 2016, the area of coca plantations in Colombia grew by 52% over the previous year, and cocaine production by 34%, according to the UN.
