Option 4 : Corundum

Corundum (Al₂O₃) is an ore of Aluminium. Calcite, Fluorspar and Dolomite are ores of Calcium.

Trick: Flour is of white color like Calcium. So, remember Fluorspar is an ore of Calcium. For Dolomite, remember MaCaDonalds. Ma> Magnesium, Ca> Calcium and Do> Dolomite. Dolomite is an ore of both Calcium and Magnesium.
