d.lakes and swamps become more numerous

thomaster · Answer

Reptiles were not strictly aquatic,
Reptiles are not dependent on the climate as their body temperature changes with the temperature of their environment. So that couldn't be it either.
More lakes and swamps doesn't seem like the right answer either. If they talk about success, they mean success in procreating, survival of the species. More living territory could be one, but the ability to lay eggs outside of the water is much more convenient for them. It's easier to protect eggs if they're outside of the water.
