Solution

The correct option is A True
  1. The rainbows are formed when sunlight falls on the raindrops.
  2. First, the light enters the water bubble through refraction.
  3. Then the total internal reflection takes place such that the water bubble acts as a prism.
  4. Then the colors will come out of a water bubble that is dispersed in the air and forms the rainbow.

Hence the given statement is true.
