Select the incorrectly matched pair from following:

Options

A. Chondrocytes - Smooth muscle cells
B. Neurons - Nerve cells
C. Fibroblast - Areolar tissue
D. Osteocytes - Bone cells

Answer

To solve the question of selecting the incorrectly matched pair, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: We need to look at the pairs given in the question. The first pair is chondrocytes and smooth muscle cells.

2. **Analyze Option A**:
- **Chondrocytes**: These are specialized cells that form cartilage. They are found in small spaces called lacunae within the cartilage matrix.
- **Smooth Muscle Cells**: These are muscle cells found in the walls of hollow organs and are not related to cartilage.
- **Conclusion for A**: Chondrocytes are not related to smooth muscle cells. Therefore, this pair is incorrectly matched.

3. **Analyze Option B**:
- **Neurons**: These are the fundamental units of the nervous system and are indeed nerve cells.
- **Conclusion for B**: This pair is correctly matched.

4. **Analyze Option C**:
- **Fibroblasts**: These are cells that produce collagen and other fibers in connective tissue, specifically in areolar tissue.
- **Areolar Tissue**: This is a type of loose connective tissue that contains fibroblasts.
- **Conclusion for C**: This pair is correctly matched.

5. **Analyze Option D**:
- **Osteocytes**: These are mature bone cells found in the lacunae of bone tissue.
- **Bone Cells**: Osteocytes are indeed bone cells.
- **Conclusion for D**: This pair is correctly matched.

6. **Final Conclusion**: The only incorrectly matched pair is **Option A: Chondrocytes and Smooth Muscle Cells**.

### Final Answer:
The incorrectly matched pair is **Chondrocytes and Smooth Muscle Cells**.
