Answer 1

The correct option is B

Their moist skin help to take in oxygen dissolved in water.

Humans can breathe on land using their lungs but they cannot breathe in water. Moist and soft skin help frogs take in dissolved oxygen from water. On land, they use lungs to breathe. They also have webbed feet that help them swim. Such animals which can live on land as well as in water are called amphibians.
