Answer 1

The correct option is A Dry skin that resists desiccation

Amphibians are cold-blooded animals that possess backbones and display features that lie between those of fish and reptiles. They spend time both in water and on land. Their larvae (not yet fully developed offspring) mature in water and breathe through gills, like fish, while adults breathe air through lungs and skin. Amphibians do not produce amniotic eggs, so they must reproduce in water. In frog development, the eggs hatch and give rise to tadpoles, small aquatic larvae that have external gills and are mainly vegetarian. As the tadpole grows, internal gills and limbs form. Amphibian skin is smooth and moist. They do not have that thick, scaly skin that is a trait of all reptiles.

So, the correct option is, 'dry skin that resists desiccation'.
