<u>c. Adult salamanders have a tail: adult frogs do not</u>
Explanation:
The salamanders, frogs, and toads are part of the amphibian family. They all live in both water and land.

The salamander offspring has only front limbs and tail, thus it can not live on land until it is fully developed, while the frog and toad offspring doesn't have any limbs at the start, only tail, thus not being able to even come out of the water. As they mature, the salamander offspring develops hind limbs as well, while retaining the tail. The frog and toad offspring develops front and back limbs, but its loses its tail.
