Among the following which one is the largest exporter of rice in the world in the last five years?

1. A

   China

   (a) China. China is the world’s largest rice producer but a modest net exporter relative to India in the years around this paper, so China is not the key.

2. B

   India

   (b) India. In the five years preceding 2019 India was the world’s largest rice exporter (non-basmati and basmati combined), ahead of Thailand and Vietnam in several of those years. That ranking is the official key.

3. C

   Myanmar

   (c) Myanmar. A regional exporter but not the world leader in that window, so not the key.

4. D

   Vietnam

   (d) Vietnam. A top-three exporter, often behind India (and sometimes Thailand), so not the key.

Summary. Official key is (b) India. Production leadership (China) is not the same as export leadership (India in that five-year span). Vietnam and Myanmar are important but smaller in the world export table. Honour the stored letter (b).
