Assertion(A) `Lambda_(m)` for weak electrolytes shows a sharp increase when the electrolytic solution is diluted.
Reason(R) For weak electrolytes degree of dissociation increases with dilution of solution.

Options

A. Both assertion and reason are true and the reason is the correct explanation of assertion.
B. Both assertion and reason are true and reason is not the correct explanation of assertion.
C. Assertion is true but the reason is false.
D. Both assertion and reason are false.

Explanation

To solve the question, we need to analyze the assertion and the reason provided:

### Step 1: Understand the Assertion
The assertion states that the molar conductivity (λ_m) for weak electrolytes shows a sharp increase when the electrolytic solution is diluted.

### Step 2: Define Molar Conductivity
Molar conductivity (λ_m) is defined as the conductivity of a solution divided by the molarity of the electrolyte. It indicates how well the ions in the solution can conduct electricity.
