The correct answer is letter B, it might be an animal that came out of the ocean and began to live on land.

This theory is one of the many theories about evolution and how life began to form here on Earth. Billions of years ago, the Earth was an inhabitable land because of the presence of poisonous gases in the atmosphere, presence of volcanoes, and the extreme temperatures that are not conducive for organisms to live in.
