Answer

**Step-by-Step Solution:**

1. **Understand the Organism**: The earthworm is a member of the phylum Annelida and is characterized by its segmented body.

2. **Identify the Reproductive System**: Earthworms are hermaphrodites, meaning they possess both male and female reproductive organs within the same individual.

3. **Locate the Testes**: The male reproductive organs, which include the testes, are located in the 10th and 11th segments of the earthworm.

4. **Count the Testes**: Each segment (10th and 11th) contains a pair of testes. Therefore, there are 2 pairs of testes in total.

5. **Calculate the Total Number of Testes**: Since each pair consists of 2 testes, the total number of testes is 2 pairs x 2 = 4 testes.

6. **Select the Correct Option**: The question asks for the total number of testes, which is 4. Therefore, the correct answer is option C (4).
