(R). Select the correct answer from the codes (A), (B), (C) and (D) as given below.

Assertion (A) : Photoelectric current increases with an increase in intensity of incident radiation, for a given frequency of incident radiation and the accelerating potential.

Reason (R) : Increase in the intensity of incident radiation results in an increase in the number of photoelectrons emitted per second and hence an increase in the photocurrent.

a

(A) Both Assertion (A) and Reason (R) are true and Reason (R) is thecorrect explanation of the Assertion (A).

b

Both Assertion (A) and Reason (R) are true, but Reason (R) is not
the correct explanation of the Assertion (A).

c

Assertion (A) is true, but Reason (R) is false.
