Solution

The correct option is D Anthozoa
Anthozoa is a class within the phylum Coelenterata. Unlike other coelenterates, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows. Some anthozoans can also reproduce asexually through budding. Hence, option D is correct.
