Given below are two statements:Statement I: Photovoltaic devices can convert optical radiation into electricity.Statement II: Zener diode is designed to operate under reverse bias in breakdown region.In the light of the above statements, choose the most appropriate answer:

  1. A
    Both Statement I and Statement II are correct
  2. B
    Both Statement I and Statement II are incorrect
  3. C
    Statement I is correct but Statement II is incorrect
  4. D
    Statement I is incorrect but Statement II is correct

Solution & Step-by-step Explanation

1. Statement I is correct: Photovoltaic cells (solar cells) use the photoelectric effect to convert light (optical radiation) directly into electrical energy.2. Statement II is correct: A Zener diode is a heavily doped p-n junction diode designed to operate in the reverse breakdown region without damage, making it useful for voltage regulation.
