Assertion. The depression in freezing point depend on the amount of the solute dissolved and not one the nature of the solute or solvent.
Reason. `K_(f)` for both has different values.

Options

A. If both assertion and reason are true, and reason is the true explanation of the assertion.
B. If both assertion and reason are true, but reason is not the true explanation of the assertion.
C. If assertion is true, but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the assertion-reason question, we need to analyze both the assertion and the reason carefully.

### Step 1: Analyze the Assertion
The assertion states: "The depression in freezing point depends on the amount of the solute dissolved and not on the nature of the solute or solvent."

- **Understanding the Assertion**: The depression in freezing point (ΔTf) is a colligative property, which means it depends on the number of solute particles in a solution and not on their identity. The formula for depression in freezing point is given by:
\[
\Delta T_f = K_f \cdot m
