The correct answer is: If both assertion and reason are true but reason is not the correct explanation of assertion
Stopping potential is a measure of maximum kinetic energy of emitted photoelectron $\left(e V_0=K_{\max }\right)$ and $K_{\max }$ depends upon the frequency of incident light but is independent of intensity.
