The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Clitellum**: The clitellum is a thickened, glandular section of the earthworm's body. It is non-segmented and can be found in specific segments of the worm, typically between segments 32 and 37. 2. **Function of the Clitellum**: The primary function of the clitellum is related to reproduction. It plays a crucial role in the formation of a cocoon for the eggs. 3. **Cocoon Formation**: During reproduction, the clitellum secretes a viscous fluid that forms a cocoon. This cocoon is where the eggs are deposited and subsequently develop. 4. **Clarifying Misconceptions**: The clitellum is not involved in copulation (the mating process), burrowing, or spermatogenesis (the formation of sperm). Its main role is in the reproductive process, specifically in cocoon formation. 5. **Conclusion**: Therefore, the clitellum of the earthworm is primarily concerned with the formation of cocoons for egg deposition. ### Final Answer: The clitellum of the earthworm is concerned with cocoon formation for the deposition of eggs. ---
