Kelp refers to which type of organism?

Explanation:
Kelp is a large brown algae, a macroalga. It’s a photosynthetic, multicellular seaweed that lives in cool coastal waters and forms underwater forests. This places kelp with algae rather than with animals or land plants. The other options represent very different groups: meroplankton are organisms with a planktonic larval stage; mangroves are terrestrial, salt-tolerant trees; krill are small crustaceans. So kelp is the type of organism that is algae.
