The stopping potential is defined as the minimum negative potential between the plates at which 
Athe saturation current becomes maximum
Bthe photoelectric current becomes zero
Cthe threshold frequency becomes zero
Dthe emitter plate starts glowing
Answer & Solution
Correct answer: B. the photoelectric current becomes zero
Stopping potential is the minimum reverse potential that prevents even the fastest photoelectrons from reaching the collector. At this potential, the photoelectric current becomes zero.
