Assertion (A): The molecular mass of polymers cannot be calculated using the boiling point or freezing point method.
Reason (R ): The boiling point method for determining the molecular masses is used for compounds stable at high temperature.

Options

A. Statement-1 is True, Statement-2 is True, Statement -2 is correct explanation for Statement -1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Explanation

To analyze the assertion and reason provided in the question, we will break down the concepts step by step.

### Step 1: Understanding the Assertion
The assertion states that "The molecular mass of polymers cannot be calculated using the boiling point or freezing point method." This is based on the fact that polymers are large macromolecules, and their molecular masses are typically too high for accurate measurements using these colligative properties.

**Hint:** Consider the nature of polymers and how their size affects the measurement techniques used for determining molecular mass.
