Assertion(A) Current stops flowing when `E_("cell")=0` .
Reason(R) Equilibrium of the cell reaction is attained.

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 (A) and the reason (R) provided.

### Step-by-step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Current stops flowing when \( E_{\text{cell}} = 0 \)".
- In electrochemical cells, current is generated due to the flow of electrons from the anode to the cathode. When the cell potential (\( E_{\text{cell}} \)) becomes zero, it indicates that there is no driving force for the electrons to flow, hence the current stops.
