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.
(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.

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 both the assertion and the reason provided.

### Step 1: Understanding the Assertion
The assertion states that "Lambda_(m) for weak electrolytes shows a sharp increase when the electrolytic solution is diluted."
- **Lambda_(m)** refers to the molar conductivity of the solution, which is a measure of how well the solution can conduct electricity. For weak electrolytes, the molar conductivity increases upon dilution due to the increased degree of dissociation.

### Step 2: Understanding the Reason
The reason states that "For weak electrolytes, the degree of dissociation increases with dilution of solution."
