Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Photodiode and photovoltaic cell both work on the principle of photovoltaic effect. When photons are incident on a direct bandgap semiconductor like GaAs, electrons are emitted generating photocurrent.
Thus, both assertion and reason re correct and reason is the correct explanation for assertion.
