Solution
The correct option is A Cutaneous
Cutaneous respiration ( respiration through skin) is the only form of respiration when the frog is under water or in hibernation. There is a rich supply of blood capillaries to the skin, which are permeable to gases. Before diffusing into blood, oxygen is first dissolved in a moist surface. The skin is kept moist either by water or by the secretion of mucous glands. As skin remains exposed to air or water, no movement of any body part is required.
Hence the correct option is A.
