Q. In which animal respiratory surface are found in more than one organ

Explanation by: Official MCQ Buddy

Frogs have multiple respiratory surfaces and can breathe through more than one organ depending on their life stage and environment:
Lungs – Used for breathing on land.
Skin (Cutaneous Respiration) – Frogs can absorb oxygen directly through their moist skin, especially when underwater.
Buccal Cavity (Buccopharyngeal Respiration) – They can also exchange gases through the lining of their mouth.
This adaptation helps them survive in both aquatic and terrestrial environments.
Why not the others?
(A) Pleura – It is a membrane around human lungs, not an animal.
(B) Human – Humans rely only on lungs for respiration.
(C) Fish – Fish use gills exclusively for breathing underwater.
