Reptiles evolved from which group of animals?

The correct answer is Option (1) → Amphibians

Vertebrate life moved from water to land in steps. Lobefin fish, with stout fins, gave rise to the first amphibians, which lived both on land and in water. The amphibians then evolved into reptiles. Reptiles lay thick-shelled eggs that do not dry up in the sun, unlike amphibian eggs, so they could breed away from water. Their modern descendants are turtles, tortoises and crocodiles.

A Brief Account of Evolution – “… These animals called lobefins evolved into the first amphibians that lived on both land and water. There are no specimens of these left with us. However, these were ancestors of modern day frogs and salamanders. The amphibians evolved into reptiles. They lay thick-shelled eggs which do not dry up in sun unlike those of amphibians. Again we only see their modern day descendents, the turtles, tortoises and crocodiles.”
