The correct answer is Option (4) → Dependency on American food grains after Independence

Option (1) Grain exports to Britain under colonial rule — Incorrect. Colonial grain exports were about food leaving the country. The wheat decision is about India having to buy grain from abroad, so it recalls dependence on foreign grain.

Option (2) Food rationing during the Second World War — Incorrect. Wartime rationing was a shortage of supply at home during colonial rule. It has nothing to do with buying grain from another country after Independence.

Option (3) The Bengal famine under colonial rule — Incorrect. The Bengal famine of 1943 was mass starvation under colonial rule. The import decision recalls a later period, the early years after Independence.

Option (4) Dependency on American food grains after Independence — Correct. Importing wheat reverses India's earlier policy of self-reliance on food grains. It brings back memories of the early years after Independence, when India depended on American food grains.
