Final answer:
Brazil is the largest coffee exporter in South America, known for its extensive coffee plantations in the Brazilian Highlands. Colombia also has a significant coffee industry but is not the top exporter. Brazilian coffee production is a key player in the global coffee market.
Step-by-step explanation:
The correct answer to the question of which South American country is the biggest coffee exporter is A) Brazil. Brazilian plantations are renowned for producing more coffee beans than any other country in the world. While more than half of all coffee came from Brazil in the 19th century, currently that number has declined, but Brazil remains the top exporter. Coffee production is especially prolific in the Brazilian Highlands, which is located away from the coastal areas.
Colombia also has a significant coffee industry and was once the world's largest coffee producer. Now, it is surpassed by Brazil and Vietnam. However, Colombia's coffee is well-known for its high quality, especially those grown at higher elevations in the Andes.
It is essential to note that while coffee is a major export of both countries, Brazilian coffee production dwarfs that of Colombia, making Brazil the leading coffee exporter in South America and the world.
