The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Ores**: Ores are naturally occurring minerals from which metals can be extracted profitably. They contain a high concentration of the desired metal. 2. **Identifying Aluminium Ore**: The ore of aluminium is primarily bauxite. Bauxite is a sedimentary rock that contains a high percentage of aluminium oxide (Al2O3) along with impurities such as silica, iron oxides, and titanium dioxide. 3. **Composition of Bauxite**: Bauxite is mainly composed of aluminium oxide in the form of hydrated alumina, which can be represented as Al2O3·2H2O. This indicates that bauxite contains both aluminium oxide and water in its structure. 4. **Conclusion**: Therefore, the ore of aluminium metal is bauxite. ---
