Final Answer :
C
Explanation :
Gases like oxygen and carbon dioxide are small enough to diffuse across a thin, moist membrane, such as the respiratory surface in the lungs or the skin in some amphibians. Therefore, option C, a thin, moist membrane, is the best choice for how gases enter and leave a mammal's body.
