The correct option is (c) Aestivation
 
For explanation: The poikilotherms use aestivation as a protective mechanism against extreme heat. The suspension of metabolic activities during summer is called aestivation. It helps in maintaining body temperature and avoids water loss in mostly cold-blooded animals such as snails, bees, tortoise, crocodile, etc.
