Solution
The correct option is B Frog
Skin and lungs are an organ of respiration in the frog. Skin is the only mode of respiration when the frog is underwater or hibernating. Skin is richly supplied with blood and is permeable to gases. It is kept moist by secretion of mucus from its glands and does not become dry out of water. That is why frogs always stay near water to keep their skin moist. During aestivation and hibernation, gaseous exchange occurs through the skin
Hence the correct option is (B)
