In Frog chromatophores occur in

Options

A. Epidermis
B. Stratum corneum of epidermis
C. Dermis
D. Stratun germinativum

Answer

To answer the question regarding where chromatophores occur in frogs, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Frog Skin Structure**:
- Frog skin is composed of two main layers: the outermost layer known as the epidermis and the innermost layer called the dermis.

2. **Identifying Layers of the Epidermis**:
- The epidermis itself is further divided into two layers:
- **Stratum Corneum**: This is the outermost layer of the epidermis.
- **Stratum Germinativum**: This is the innermost layer of the epidermis.

3. **Understanding the Dermis**:
- The dermis is also composed of two layers:
- **Stratum Spongiosum**: This is the outer layer of the dermis.
- **Stratum Compactum**: This is the innermost layer of the dermis.

4. **Locating Chromatophores**:
- Chromatophores are specialized cells that contain pigments. In frogs, these chromatophores are located in the **stratum spongiosum**, which is part of the dermis.

5. **Conclusion**:
- Based on the information, we can conclude that chromatophores in frogs occur in the **dermis**, specifically in the **stratum spongiosum**.

### Final Answer:
The correct answer is **Dermis** (Option 3).
