Solution

The correct option is C If the assertion is true but the reason is false
Contractile vacuole in Amoeba is a single, clear rounded pulsating structure which is filled with a watery fluid and enclosed by a unit membrane. It helps in the osmoregulation and excretory activities. Digestion in Amoeba occurs in the food vacuoles. These are spherical species small and large, contain water and food in various phases of digestion. As soon as the egestion of non-digestible food occurs through body these get disappear.
So, the correct answer is 'If the assertion is true but the reason is false'.
