C Correct answer
Explanation

Jellyfish have existed for at least 500 million years, making them older than sharks, which appeared about 400 to 450 million years ago. Dinosaurs and humans appeared much later in Earth's history. This makes jellyfish one of the oldest multi-organism animal groups on the planet.
