The correct option is B Frog
Frogs aren't restricted to breathing only through their lungs. Frogs that spend the coldest times of the year inside of the mud or within rotten heaps of leaves receive their necessary oxygen through their skin. This is referred to as cutaneous gas exchange. They use their skin to soak in the oxygen their bodies require. When frogs hibernate, they utilize the skin for any and all breathing. Damp skin is a must for subcutaneous gas exchange. If a frog's skin becomes dry, it will no longer be able to take in oxygen. Thus, option B is correct.
