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 \( |V_z| \ge \pm V \ge |V_0| \) where \( V_0 \) is the threshold voltage and \( V_z \) is the breakdown voltage.
In the light of the above statements, choose the correct answer from the options given below.
