Solution
The correct option is D Planula
Stereogastrula (also known as parenchymula), stomogastrula and amphiblastula are poriferan larvas found in leucosolenia, sycon etc.
Planula is the free-swimming, ciliated, flattened, bilaterally symmetric larval form of various cnidarian species. Planula larva is produced by the polyp form in sea anemones and other anthozoans and by the medusa form in most other cnidarians. Hence option D is correct.
