Which two specialized structures allow reptiles to live on land

It is D (lungs) because they can't use gills on land. Gills help them breathe underwater and lungs are the only other way for them to breathe

It is also C (scaly skin) because the reptiles have dry, scaly skin. But they don't need moisturizer! Their special covering actually helps them hold in moisture and lets them live in dry places.
