Cartilage is a type of

Options

A. Connective tissue
B. Epithelial tissue
C. Skeletal tissue
D. Muscular tissue.

Explanation

### Step-by-Step Solution:

1. **Identify the Type of Tissue**: The question asks what type of tissue cartilage is classified as. The options provided are connective tissue, epithelial tissue, skeletal tissue, and muscular tissue.

2. **Understand Cartilage**: Cartilage is known to be a type of tissue that provides support and flexibility. It is softer and more pliable compared to bone.

3. **Connective Tissue Classification**: Cartilage falls under the category of connective tissue. Connective tissues are characterized by their ability to support, bind, and protect other tissues and organs in the body.

4. **Characteristics of Cartilage**: Cartilage is a rubber-like padding that covers and protects the ends of long bones, joints, and nerves. It is flexible due to the presence of specialized cells called chondrocytes, which contain a substance known as chondroitin sulfate.

5. **Evaluate the Options**:
- **Connective Tissue**: Correct, as cartilage is a type of connective tissue.
- **Epithelial Tissue**: Incorrect, as epithelial tissues line surfaces and do not provide the same support as connective tissues.
- **Skeletal Tissue**: Incorrect, as skeletal tissue refers to the bones themselves, not the cartilage.
- **Muscular Tissue**: Incorrect, as muscular tissue is involved in movement and does not include cartilage.

6. **Conclusion**: Based on the analysis, the correct answer is that cartilage is a type of **connective tissue**.
