Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion(A): In frog, moist skin serves as an organ for gas exchange.

Reason(R): The lungs of frog cannot exchange gases even while it is on land.

In light of the above statements, choose the correct answer from the options given below.

The correct answer is option (3).(A) is true but (R) is false.

Explanation:

Frogs are amphibians, and they have moist, permeable skin that allows for gas exchange. Oxygen can diffuse through the skin and into the bloodstream, while carbon dioxide can diffuse out. This process is called cutaneous respiration and is important for frogs on both land and water.

However, it is not true to state that the lungs are non-functional. Frogs exhibit pulmonary respiration when there is a high requirement for oxygen.
