B. lacuna
C. chromatophores
D. adipose cells

Answer

To answer the question "The matrix of bone and cartilage can be distinguished by the presence of," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components**: First, we need to recognize that both bone and cartilage are types of connective tissues, but they have different structures and functions.

2. **Identify the Key Features**: The matrix of bone is mineralized and contains specific structures that are not found in cartilage. In contrast, cartilage has a more flexible matrix.

3. **Focus on Haversian Canal**: One of the distinguishing features of bone is the presence of the Haversian canal. This canal runs through the bone and contains blood vessels and nerves, which are essential for the bone's nourishment and communication.

4. **Differentiate from Cartilage**: Cartilage lacks Haversian canals. Instead, it has a more homogeneous matrix and relies on diffusion for nutrient supply.

5. **Conclude the Answer**: Therefore, the presence of Haversian canals is a key distinguishing factor between the matrix of bone and cartilage.

### Final Answer:
The matrix of bone and cartilage can be distinguished by the presence of **Haversian canal**.
