Solution
The correct option is D Lungs
Both snakes and frogs (adults) respire through lungs. Frog tadpoles breathe through gills under water, but adult frogs breathe through lungs and moist skin.
Diaphragm is absent in both frogs and snakes. Only frogs utilize their buccal cavity to carry out buccopharyngeal respiration.
Being an amphibian, the frog shows different modes of respiration based on environmental and physiological conditions. Frogs mainly respire either via their skin, mouth, lungs, or gills. Adult frogs lose their gills and respire via lungs, skin and their mouth. The lack of a diaphragm makes them use their mouth, lungs, nostrils, and mouth to expel gases.
So, the correct option is "lungs".
