four limbs
B
laying eggs in water
C
scaly skin
D
using lungs for breathing
Explanation: 

Detailed explanation-1: -Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the babies, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do. As the tadpoles grow, they develop legs and lungs that allow them to live on land.

Detailed explanation-2: -These can live both on land and in water. They are ectothermic animals, found in a warm environment. Their body is divided into head and trunk. The skin is smooth and rough without any scales, but with glands that make it moist. They have no paired fins. More items

Detailed explanation-3: -Amphibians are cold-blooded. Amphibians live on land as well as in the water. Amphibians lay eggs to reproduce their species (nearly all amphibians lay their eggs in or near water); They have moist, smooth skin. Amphibians have webbed feet that help them swim more efficiently.
