D
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Option D is the graph of stopping potential Vo against the frequency of the incident light I. The straight line graph cuts the intercept I = threshold frequency. As the frequency of the incident light increases above this point(threshold frequency), the stopping potential corresponding to the kinetic energy of the photoelectron also increases.
