Arrange the following coffee producing countries in descending order of their coffee production (2016, quantity) and select the correct answer from the codes given below: A) Colombia B) Vietnam C) Brazil D) Indonesia

The correct order by 2016 output is Brazil (C), Vietnam (B), Colombia (A), Indonesia (D), which is option B. Brazil was the world's largest producer by a wide margin, at roughly 2.7 million tonnes of green coffee. Vietnam came next at about 1.6 million tonnes, mostly Robusta. Colombia, the famous Arabica exporter, produced about 0.8 million tonnes. Indonesia, mainly Robusta from Sumatra and Java, was close to 0.6 million tonnes.

• Option A puts Indonesia first and Brazil last, which reverses the real hierarchy.
• Option C places Vietnam above Brazil, which was never true in 2016.
• Option D puts Colombia above Vietnam, which is the usual mix-up because Colombia's brand is so strong.

The core concept is the global distribution of plantation crops and the split between Arabica and Robusta, which is useful for Economic Geography. For Mains, compare this with India, where Karnataka leads, followed by Kerala and Tamil Nadu, and link it to the Coffee Board and export competitiveness. Figures are approximate, and Brazil and Vietnam remain the top two producers in recent years.

Trap: Aspirants rank Colombia above Vietnam because they associate coffee with Colombian Arabica, but Vietnam's volume is far larger.
