The Attempt at a Solution
As frequency is decreased to threshold, no. of emitted electrons will remain same, but their maximum kinetic energy will decrease. So, the current should decrease slowly.
For frequency less than the threshold frequency, no electron will be emitted. So, the current should fall down to 0 at threshold frequency and for frequency less than threshold frequency.Option(c) meets the above two conditions. So, this should be the correct option. Right?
