• D. Shark

Answer: (A)

Reptiles are a class of vertebrates defined by dry, scaly skin and typically laying amniotic eggs, which allow development away from water. Snakes fit this description: they are covered in scales, are ectothermic, and belong to the reptile lineage. The other options belong to different groups—eagles are birds with feathers and flight muscles, frogs are amphibians with moist skin and a life cycle that usually starts in water, and sharks are fish with gills and a backbone of cartilage or bone.
