• C. In water – skin, buccal cavity
• D. On land – skin, lungs, gills

Answer 1

The correct option is B

On land – skin, buccal cavity

Respiration -- the exchange of gases between an organism and its environment -- in adult frogs can occur in three different ways, either independently or in tandem. Adult frogs breathe through their lungs and exchange gases through their skin and the lining of their mouths. At the larval stage of their development, frogs lack functional lungs but are able to take in oxygen through a set of gills.
