Supporting connective tissues found in the body are :

Options

A. muscle and bone
B. mast cells and adipocytes
C. cartilage and bone
D. collagen and reticular fibers

Answer

To answer the question about the supporting connective tissues found in the body, we can analyze the options provided step by step.

### Step-by-Step Solution:

1. **Understanding Supporting Connective Tissues**:
- Supporting connective tissues are those that provide structural support to the body and its organs. They include tissues that help maintain the shape and integrity of various body structures.

2. **Analyzing Option A (Muscle and Bone)**:
- Muscle tissue, specifically skeletal muscle, is primarily responsible for movement and does not serve as a supporting connective tissue.
- Bone, however, is a type of supporting connective tissue.
- Since muscle is not a supporting connective tissue, this option is incorrect.

3. **Analyzing Option B (Mast Cell and Adipocyte)**:
- Mast cells are involved in immune responses, while adipocytes (fat cells) are associated with energy storage and endocrine functions.
- Neither of these cells is classified as supporting connective tissues. Therefore, this option is also incorrect.

4. **Analyzing Option C (Cartilage and Bone)**:
- Cartilage is a type of supporting connective tissue that provides flexibility and support to various structures, such as joints and the respiratory tract.
- Bone is another type of supporting connective tissue that provides rigidity and strength to the skeletal system.
- Both cartilage and bone serve the function of supporting other tissues and organs, making this option correct.

5. **Analyzing Option D (Collagen and Reticular Fiber)**:
- Collagen and reticular fibers are components of connective tissues but are not classified as supporting connective tissues themselves. They provide structural support within various connective tissues but do not constitute a type of supporting connective tissue.
- Therefore, this option is incorrect.

### Conclusion:
The correct answer is **Option C: Cartilage and Bone**, as both are classified as supporting connective tissues in the body.
