Which of the following is/are the compound of aluminium?

Options

A. horn silver
B. bauxite
C. corrundum
D. Diaspore

Explanation

To determine which of the given options are compounds of aluminium, we can analyze the chemical formulas provided for each compound.

### Step-by-Step Solution:

1. **Identify the Compounds**: We need to look at the names and formulas of the compounds provided in the question.

2. **Check Each Compound**:
- **Horn Silver**: The formula is AgCl. This compound contains silver (Ag) and chlorine (Cl), but does not contain aluminium (Al). Therefore, it is **not** a compound of aluminium.
- **Bauxite**: The formula is Al2O3·3H2O. This compound contains aluminium (Al) as part of its structure. Therefore, it **is** a compound of aluminium.
- **Corundum**: The formula is Al2O3. This compound also contains aluminium (Al) as part of its structure. Therefore, it **is** a compound of aluminium.
- **Dyspore**: The formula is AlO(OH). This compound contains aluminium (Al) as well. Therefore, it **is** a compound of aluminium.

3. **Conclusion**: Based on the analysis:
- Horn Silver (AgCl) is **not** a compound of aluminium.
- Bauxite (Al2O3·3H2O) **is** a compound of aluminium.
- Corundum (Al2O3) **is** a compound of aluminium.
- Dyspore (AlO(OH)) **is** a compound of aluminium.

Thus, the compounds of aluminium from the given options are Bauxite, Corundum, and Dyspore.

### Final Answer:
The compounds of aluminium are: **Bauxite (Al2O3·3H2O), Corundum (Al2O3), and Dyspore (AlO(OH))**.
