Which correctly compares a jellyfish and a coral?

A jellyfish has a medusa stage and a polyp stage in its life cycle. It typically reproduces sexually as a medusa and asexually as a polyp, so it reproduces across two stages. A coral is generally a polyp and does not have a medusa stage. Therefore, the correct choice is “Only the jellyfish is a medusa, and it reproduces in two stages.”
