The country at the top in terms of percentage of total coffee production in the world is

The correct answer is B, Brazil. Brazil produces roughly a third of the world's coffee, far ahead of any other country, and it has held the top position for many decades.

• Colombia (A): It is a major producer and famous for high-quality washed Arabica, but its total output is well below Brazil's. In total volume, Vietnam has usually ranked second, which is a common point of confusion.
• India (C): India is a significant producer with a share of only a few percent, grown mainly in Karnataka, Kerala and Tamil Nadu. It is not near the top.
• Ethiopia (D): Ethiopia is the birthplace of Arabica and Africa's largest coffee producer, but it is a distant second or lower in the world ranking, not the leader.

The core concept is the global distribution of coffee production and the difference between Arabica and Robusta. Brazil's dominance is a useful reference for the plantation-crop segment of Indian Agriculture and for India's coffee export policy, which is governed by the Coffee Act, 1942, and the Coffee Board under the Ministry of Commerce.

Trap: Aspirants often mix up quality-based fame (Colombia, Ethiopia) with total volume. For this question, the criterion is total production, so Brazil is the answer.
