The correct option is A Camel
Camels live in the desert which is a very hot place. The camel has adapted itself to these conditions in the following way - The camel's muscles can withstand the shortage of water and can shrink considerably. Once the water is available, the camel can drink sufficient water and the muscle swell up. When deprived of water, the camel passes out very little urine and thick urine.
None of the other animals is found in a desert habitat, so it is unlikely that the adaptations describe them.
