The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Frog's Respiration**: Frogs belong to the class Amphibia and have a unique respiratory system that allows them to breathe both in water and on land. 2. **Identifying Hibernation**: Hibernation, also known as winter sleep, occurs when frogs enter a state of dormancy to survive extreme environmental conditions. During this time, they often submerge themselves in water. 3. **Respiratory Surfaces**: Frogs have three main respiratory surfaces: - **Lungs**: Used for breathing air when on land. - **Skin**: Used for gas exchange when submerged in water. - **Buccopharyngeal Cavity**: The lining of the mouth can also assist in respiration. 4. **Respiration During Hibernation**: When a frog is hibernating or completely submerged in water, it cannot use its lungs because they require air. Instead, it relies on its skin for respiration, which allows it to absorb oxygen directly from the water. 5. **Conclusion**: Therefore, when a frog is in hibernation or completely submerged in water, it can respire only through its skin. **Final Answer**: The frog can respire only through its skin when in hibernation or completely submerged in water. ---

Statement I: Imagine holding two identical bricks under water. Brick A is completely submerged just below the surface of water, while brick B is at a greater depth. The magnitude of force exerted by the person (on the brick) to hold brick B in place is the same as magnitude of force. exerted by the person (on the brick) to hold brick A in place. Statement II: The magnitude of buoyant force on a brick completely submerged in water is equal to the magnitude of weight of water it displaced and does not depend on the depth of the brick in water.
