Photoelectric Effect Intensity and Photoelectrons

In the following question, a statement of Assertion (A) is followed by a statement of Reason (R).
Assertion (A): On increasing intensity of light, more number of photoelectrons are emitted.
Reason (R): The number of electrons emitted does not depend on intensity of incident radiations
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true statement but (R) is false
Both (A) & (R) are false statements

Solution:

The number of emitted photoelectrons per second is directly proportional to the intensity of incident light above the threshold frequency. Thus, Assertion is true but Reason is false.
