Answer: (C)

Verified step by step guidance

1. Understand the anatomy and function of coral polyps: Coral polyps are small, soft-bodied organisms that are part of the coral colony. They have tentacles surrounding their central mouth.
2. Learn the primary role of tentacles in coral polyps: Tentacles are equipped with specialized cells called cnidocytes, which contain nematocysts (stinging structures) used to capture food particles.
3. Clarify why tentacles are not used for photosynthesis: Coral polyps rely on symbiotic algae called zooxanthellae for photosynthesis, not their tentacles. The tentacles are specialized for feeding, not energy production.
4. Explain why tentacles do not release reproductive gametes: Coral polyps release gametes directly into the water during spawning events, but this process does not involve the tentacles.
5. Conclude that the tentacles' primary purpose is to capture food particles from the surrounding water, using their stinging cells to immobilize prey and bring it to the mouth for digestion.
