The correct option is D Both B and C
- A contractile vacuole is a sub-cellular organelle found in few protozoans.
- It is a specialized vacuole which helps in regulating the quantity of water inside cell (osmoregulation- maintaining constant osmotic pressure of the fluids of an organism).
- It is a part of the protective mechanism which prevents the cell from absorbing too much water and also prevents the rupturing of the cell created due to excessive internal pressure.
- It also expels out the waste material (ammonia collected from the intercellular fluid) to the cell exterior.
