(D) Reptilia and Amphibians differ in several key aspects:$1$. Skin: Amphibians have moist,glandular skin without scales,whereas Reptiles have dry,cornified skin with epidermal scales or scutes.$2$. Structure of Heart: Most Amphibians have a $3$-chambered heart ($2$ atria and $1$ ventricle),while most Reptiles also have a $3$-chambered heart,but the ventricle is partially divided (except in Crocodiles,which have a $4$-chambered heart).$3$.
