Solution

The correct option is C A is false but B is true.
If the frequency light source is doubled then the maximum kinetic energy of the photoelectrons will be doubled.

And if the intensity of a light source is doubled then the saturation photocurrent will also increase.

So, A is false but B is true.

So, the answer is option (C).
