Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason RAssertion 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 $\displaystyle \left|\mathrm{V}_{\mathrm{z}}\right|> \pm \mathrm{V} \geq\left|\mathrm{V}_0\right|$ where $\displaystyle \mathrm{V}_0$ is the threshold voltage and $\displaystyle \mathrm{V}_{\mathrm{z}}$ is the breakdown voltage.In the light of the above statements, choose the correct answer from the options given below
