Answer: A

Aestivation is seen in amphibians.

Aestivation is 'summer sleep': a state of dormancy that some animals enter to survive heat and drought. Frogs and toads, whose moist skin dries out easily, burrow into mud and remain inactive until the rains return; lungfish, snails and some insects do the same.

The chimpanzee does not become dormant at all. Squirrels are known for winter dormancy (hibernation) in cold regions, the opposite season. Salmon respond to the seasons by migrating between sea and river to breed, not by aestivating.
