Question

Which of the following is the respiratory organ of the frog?

• A. Lungs
• B. Gills
• C. Moist skin and oral cavity
• D. None of the above

Answer 1

Answer: (C)

Moist skin and oral cavity

The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. While completely submerged all of the frog's respiration takes place through skin.

So, option C is the correct option.
