C Correct answer
Explanation

Lime (calcium carbonate or calcium oxide) is used to reclaim acidic soils because it neutralizes soil acidity by raising the pH level. The calcium in lime replaces hydrogen and aluminum ions, making nutrients more available to plants. Sulphur would make soil more acidic, while Gypsum is used for sodic/alkaline soils, not acidic ones.
