Assertion :- Work function of a metal increases with increase in intensity of incident light.
Reason :- Maximum kinetic energy of ejected
\( P \) photoelectrons depends upon the intensity of incident light.
(1) A
(2) \( \mathrm{B} \)
(3) \( \mathrm{C} \)
(4) D
(A) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
(B) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
(C) Assertion is correct, but reason is wrong statement.
(D) Assertion is wrong, but reason is correct statement.
