Question

Which is/are the respiratory organ(s) present in frog?

• A. Only lungs
• B. Lungs, skin and grills
• C. Lungs and skin
• D. Only skin

Answer 1

The correct option is C Lungs and skin

The skin of an earthworm feels moist and slimy on touching. Gases can easily pass through them. Though frogs have a pair of lungs like human beings, they can also breathe through their skin, which is moist and slippery.

So, the correct answer is 'lungs and skin'.
