D Correct answer
Explanation

Birds are warm-blooded (endothermic) organisms because they maintain a constant internal body temperature regardless of the external environment, using metabolic heat production. Fish, frogs, and snakes are all cold-blooded (ectothermic) - their body temperature changes with their surroundings and they rely on external heat sources to regulate their temperature.
