Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : Photodiodes are used in forward bias usually for measuring the light intensity.
Reason R : For a p-n junction diode, at applied voltage V the current in the forward bias is more than the current in the reverse bias for $\mathrm{|{V_z}| > \pm v \ge |{v_0}|} where \mathrm{v_0} is the threshold voltage and \mathrm{V_z}$ is the breakdown voltage.
In the light of the above statements, choose the correct answer from the options given below
