Earthworms can feel the vibrations of the gound by presence of

Options

A. Buccal receptors
B. Photoreceptors
C. Epidermal receptors
D. Chemoreceptors

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how earthworms can detect vibrations in the ground. It's important to identify the type of receptors that are responsible for this ability.

2. **Reviewing the Options**:
- **Buccal Receptors**: These are located in the buccal chamber and are primarily involved in detecting chemical stimuli (taste and smell). They are not responsible for detecting vibrations.
- **Photoreceptors**: These are light-sensitive receptors found on the dorsal surface of the earthworm's body. They help the organism detect light but do not play a role in sensing vibrations.
- **Epidermal Receptors**: These receptors are distributed throughout the body, particularly on the lateral sides and ventral surface. They are responsible for tactile stimulation and can detect vibrations in the environment.
- **Chemoreceptors**: Similar to buccal receptors, these are involved in detecting chemical stimuli and are not responsible for sensing vibrations.

3. **Identifying the Correct Answer**: Among the options, epidermal receptors are the ones that can detect vibrations in the ground. They are sensitive to various external stimuli, including vibrations caused by movement in the soil.

4. **Conclusion**: The correct answer to the question is **epidermal receptors**.

**Final Answer**: Earthworms can feel the vibrations of the ground by the presence of **epidermal receptors**.
