Which of the following statements is correct?

Options

A. Bauxite is an ore of aluminium
B. Magnetite Is an ore of manganese
C. Haematite is an ore of mercury
D. Pyrite is an ore of phosphorus

Answer

To determine which of the statements is correct, we will analyze each statement one by one.

### Step 1: Analyze the first statement
**Statement:** Bauxite is an ore of Aluminium.
**Analysis:** Bauxite is indeed an ore of aluminium. Its chemical formula is Al2O3·xH2O, indicating that it contains aluminium oxide along with water molecules.
**Conclusion:** This statement is **correct**.

### Step 2: Analyze the second statement
**Statement:** Magnetite is an ore of manganese.
**Analysis:** Magnetite has the chemical formula Fe3O4, which means it is primarily an iron ore, not manganese.
**Conclusion:** This statement is **incorrect**.

### Step 3: Analyze the third statement
**Statement:** Hematite is an ore of mercury.
**Analysis:** Hematite has the chemical formula Fe2O3, and it is an iron oxide. It is not associated with mercury.
**Conclusion:** This statement is **incorrect**.

### Step 4: Analyze the fourth statement
**Statement:** Pyrite is an ore of phosphorus.
**Analysis:** Pyrite has the chemical formula FeS2. It is primarily an iron sulfide and does not contain phosphorus.
**Conclusion:** This statement is **incorrect**.

### Final Conclusion
After analyzing all the statements, we find that the only correct statement is:
- **Bauxite is an ore of Aluminium.**
