ANSWER

B. Nematocysts.
Nematocysts or cnidocysts represent the common feature of all cnidarians. They are large organelles produced from the Golgi apparatus as a secretory product within a specialized cell, the nematocyte or cnidocyte.
Nematocysts are predominantly used for prey capture and defense, but also for locomotion.
Cnidoblasts are used for anchorage, defense, and to capture the prey
