The following graph represents

The following graph represents
  1. forward bias characteristics of a solar cell
  2. reverse bias characteristics of a Zener diode
  3. reverse bias characteristics of a photodiode
  4. forward bias characteristics of a LED

Solution

With increasing voltage, the LED's current rises, leading to light emission due to charge carrier recombination.
