In Pheretima, the glands that help in binding the worms during copulation are -

Options

A. Prostate gland
B. Albumin glands
C. Accessory glands
D. Mucous glands

Answer

To solve the question regarding the glands in Pheretima (earthworm) that help in binding the worms during copulation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the specific gland in earthworms that facilitates the binding of two worms during copulation.

2. **Identify the Options**: The options provided are:
- A) Prostate gland
- B) Albumin gland
- C) Accessory gland
- D) Mucus gland

3. **Recall the Function of Each Gland**:
- **Prostate Gland**: Typically associated with the male reproductive system in vertebrates, not relevant to earthworms.
- **Albumin Gland**: While it plays a role in reproduction, it is not primarily responsible for binding during copulation.
- **Accessory Gland**: Known to secrete substances that help in the attachment of earthworms during copulation.
- **Mucus Gland**: Produces mucus but is not specifically known for binding during copulation.

4. **Determine the Correct Answer**: Based on the functions of the glands, the **Accessory gland** is the one that facilitates the binding of earthworms during copulation. This gland's secretion is crucial for the attachment of the two worms.

5. **Location of the Accessory Gland**: The accessory glands are located in segments 17 and 19 of the earthworm, specifically on the ventral side of the body wall.

6. **Final Answer**: Therefore, the correct answer to the question is **C) Accessory gland**.
