The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Earthworm Anatomy**: The earthworm belongs to the phylum Annelida and has a segmented body structure. Each segment has specialized structures, including reproductive organs. 2. **Identifying Genital Apertures**: In earthworms, each genital aperture consists of three distinct openings. Two of these are associated with the vasa differentia (the ducts that transport sperm), and one is associated with the prostatic gland. 3. **Role of Prostatic Secretion**: The prostatic gland in earthworms produces a secretion that plays a crucial role in reproduction. This secretion is essential for the proper functioning of sperm. 4. **Functions of Prostatic Secretion**: The prostatic secretion has two primary functions: - It activates the sperm, which is necessary for the sperm to be capable of fertilization. - It aids in the motility of sperm, allowing it to move effectively towards the egg for successful reproduction. 5. **Conclusion**: Based on the functions of prostatic secretion, the correct answer to the question is that it is helpful for the **activation of sperm**. **Final Answer**: The prostatic secretion in earthworms is helpful for the activation of sperm. ---
