Solution

The correct option is B Anthozoans
'Sea fans' are similar to 'sea pens', both of which are soft corals. They are sessile colonial cnidarians found throughout the oceans of the world, belonging to the class of Anthozoa. They belong to the Anthozoa because they do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula.
