• C. On land - skin, lungs, gills
• D. On land - skin, buccal cavity

Answer 1

The correct option is D On land - skin, buccal cavity

• Frogs can live both on land and in freshwater and belong to class Amphibia of phylum Chordata.
• Frogs respire on land and in the water by two different methods. In water, skin acts as a respiratory organ(i.e cutaneous respiration) by diffusion.
• On land, the buccal cavity, skin and lungs act as the respiratory organs. The respiration by lungs is called pulmonary respiration. Hence, on land adult frog breathe with skin, buccal cavity.

So, the correct answer is 'on land skin, buccal cavity'.
