Answer: B) Brazil
According to Wikipedia, "Brazil remains the largest coffee exporting nation, but in recent years Vietnam has become a major producer of robusta beans. Colombia is the third exporter and the largest producer of washed arabica coffee." Coffee is one of the world's most popular beverages: "Coffee ingestion on average is about a third of that of tap water in North America and Europe. Worldwide, 6.7 million metric tons of coffee were produced annually in 1998–2000, and the forecast is a rise to 7 million metric tons annually by 2010."
