Explanation

To identify the compounds A, B, C, and D in the given reactions, we can analyze each step carefully.

### Step-by-Step Solution:

1. **First Reaction: Bauxite + Charcoal + Chlorine → A + CO**
- Bauxite is primarily composed of aluminum oxide (Al₂O₃).
- When bauxite is reacted with charcoal (carbon) and chlorine gas at high temperatures, it produces aluminum chloride (AlCl₃) and carbon monoxide (CO).
- Therefore, A = AlCl₃.
