Given below are two statements : one is ...

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: The photoelectric effect does not takes place, if the energy of the incident radiation is less than the work function of a metal.
Reason R : Kinetic energy of the photoelectrons is zero, if the energy of the incident radiation is equal to the work function of a metal.
In the light of the above statements, choose the most appropriate answer from the options given below.

A

Both A and R are correct and R is the correct explanation of A

B

Both A and R are correct but R is not the correct explanation of A

C

A is correct but R is not correct
