The correct option is B Salamander
Salamander lays eggs in water. In adult form, they can survive both on land and in water. Respiration occurs through gills, lungs, skin, and the membranes of mouth and throat. Their skin secretes mucus which helps it slip from predators and also offers the least resistance while swimming. They have a three-chambered heart. Attributing to these characteristics they are placed under the class Amphibia. On the other hand, lizard, crocodile, and snakes belong to the class Reptilia.
