The constituents of a heterogeneous mixture are X, Y and Z. If mixture containing X and Y is taken, X can be separated using magnetic separation, Y and Z can be separated using distillation method. Which of the following best identifies X, Y and Z respectively?

Options

A. Iron, salt, water
B. Sulphur, carbon disulphide, water
C. Gun powder, common salt, water
D. lodine, sand, alcohol

Explanation

To solve the problem, we need to identify the substances X, Y, and Z based on the separation methods mentioned: magnetic separation and distillation.

### Step-by-Step Solution:

1. **Understanding the Separation Methods**:
- The problem states that X can be separated using magnetic separation. This implies that X has magnetic properties.
- Y and Z can be separated using distillation, which is typically used for separating components based on their boiling points.

2. **Identifying X**:
- Since X can be separated using magnetic separation, it is likely a magnetic material. Common examples of magnetic materials include iron, nickel, and cobalt.
- Given the context of a mixture, X is most likely **iron** (Fe), as it is a common magnetic substance.

3. **Identifying Y and Z**:
- The remaining components Y and Z can be separated by distillation. A common mixture that can be separated this way is saltwater, where:
- Y could be **salt** (sodium chloride, NaCl).
- Z could be **water** (H₂O).
- Distillation works here because when saltwater is heated, water evaporates and can be condensed back into liquid, leaving the salt behind.

4. **Final Identification**:
- Therefore, we can conclude:
- X = Iron (Fe)
- Y = Salt (NaCl)
- Z = Water (H₂O)

### Conclusion:
The best identification of X, Y, and Z respectively is:
- X = Iron
- Y = Salt
- Z = Water
