The correct answer is – D. Ecuador.

Even though Ecuador is the smallest of the Andean countries, it is a country that has the perfect conditions for the farming of bananas and plantains, and it uses it to the maximum. Big portion of the economy of this South American country is actually based on the exports of bananas. In the last statistical year of 2017, Ecuador ranked as number one producer of bananas in the world, exporting this fruit to 71 countries throughout the whole world, and earning a staggering 3 billion USD in this year alone.
