Explanation

Option B is correct: India has consistently held the position of the largest exporter of rice in the world, commanding between 30% and 40% of the total global rice trade:

– Bolstered by substantial exports of both aromatic Basmati rice and non-Basmati white/parboiled rice to markets across Africa, the Middle East, and Asia, India surpassed traditional exporters like Thailand and Vietnam.
– While China is the world’s largest producer and consumer of rice, it is a net importer rather than the largest exporter.

Hence, the largest exporter of rice is India — Option B.
