Options

A. Sodium
B. Potassium
C. Magnesium
D. Aluminum

Explanation

To determine which elements Carnalite is an ore of, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Composition of Carnalite**:
- Carnalite is a mineral that has the chemical formula KCl·MgCl2·6H2O. This indicates that it contains potassium (K), magnesium (Mg), chlorine (Cl), and water (H2O).

2. **Analyze the Elements Present**:
- From the formula, we can see that Carnalite contains potassium (K) and magnesium (Mg).

3. **Determine the Ore Status**:
- An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted. In this case, Carnalite is a source of both potassium and magnesium.

4. **Conclude the Elements**:
- Therefore, we can conclude that Carnalite is an ore of potassium and magnesium.

### Final Answer:
Carnalite is an ore of potassium (K) and magnesium (Mg).
