Hint: Frogs spend the coldest duration of the year by hibernating inside the mud or hide within decomposed heaps of leaves. Cutaneous Respiration facilitates frogs to breathe in hibernation.

Complete answer: The skin of the frog provides an extensive surface for the exchange of gases. It is thin, lavishly provided with blood, and kept moist by the mucus and water. The cutaneous respiration is always carried out. During hibernation (winter sleep) and aestivation (summer sleep), it is the main technique for respiration in a frog. This is also called cutaneous respiration.
We all know that frogs undergo hibernation. Now we will know how they breathe during hibernation.
They get their necessary oxygen through their skin. This process is known as cutaneous gas exchange.
The skin of the frog is utilized to soak in the oxygen their bodies require.
When frogs hibernate, they utilize the skin for breathing.
Damp skin is the ultimate requirement for subcutaneous gas exchange.
If the frog’s skin gets evaporated or dried up, it will no longer get any oxygen to take in.

So the correct answer is (D) 'Skin only’.

Additional Information:
Numerous types of frogs snooze their way through the winter, even though not all of them do. Frogs that dwell in areas with colder climates get through the chilling winter months by going into hibernation.

The skin is permeable to respiratory gases and transports oxygen to the body cells for respiration. They regularly invest the energy concealed somewhere down in the soil, in the mud underwater or hidden midst of foliage or rotting plants. There is comparability to be watched like numerous different creatures.
