In earthworm, the sperms mature in

Options

A. Testis sacs
B. testes
C. seminal vesicle
D. vasa deferentia

Explanation

**Step-by-Step Solution:**

1. **Understanding Earthworm Reproduction**: Earthworms are bisexual organisms, meaning they possess both male and female reproductive organs. This allows them to produce both sperm and eggs.

2. **Sperm Production**: The production of sperm occurs in the testes. In earthworms, there are two testes that generate sperm.

3. **Sperm Storage and Maturation**: After being produced in the testes, the sperm move to the seminal vesicles. The seminal vesicles are responsible for storing the sperm, and during this time, the sperm also mature.

4. **Pathway of Sperm**: Once the sperm are mature in the seminal vesicles, they travel through the spermiducal funnel and then into the vasa deferentia. The vasa deferentia are ducts that transport the sperm to the common prostatic or spermatic duct.

5. **Release of Sperm**: Finally, the mature sperm are released outside the body through the male genital apertures.

6. **Conclusion**: Therefore, the correct answer to the question "In earthworm, the sperms mature in" is **seminal vesicle**.

**Final Answer**: Seminal vesicle (Option C)
