Solution

The correct option is A Biological process
  • The photoreceptor cells convert the light into electrical impulses which are transmitted to the brain through the nerve cells.
  • The retina converts the light energy into electrical impulse.
  • The electrical impulse is then carried to the brain by the optic nerve.
  • So, the correct answer is 'Biological process'.
