Solution
The correct option is B Moist skin
During hibernation, the frog's metabolic rate is very low. Their heart beat is greatly reduced and the amount of oxygen needed to survive is a fraction of what is required when the frog is active. Cutaneous respiration is sufficient to sustain the frogs. So, when the frog hibernates, the entire respiration takes place through the moist skin. So, the correct answer is option B.
