Solution
The correct answer is "the amniotic egg."
Reptiles, birds, and mammals are all amniotes, a group of animals that have evolved the amniotic egg. This type of egg contains a special membrane, the amnion, which protects and hydrates the embryo. This allows these animals to reproduce on land, away from water. The evolution of the amniotic egg is a key factor that has enabled these animals to inhabit a wide range of terrestrial environments.
