Bone cartilage is found in -

Options

A. Long arteries
B. Long muscles
C. Long nerves
D. Long bones

Explanation

**Step-by-Step Solution:**

1. **Understanding Cartilage**: Begin by recognizing that cartilage is a type of connective tissue that is softer and more flexible than bone. This flexibility allows for movement and provides support in various parts of the body.

2. **Location of Cartilage**: Cartilage is commonly found in areas where flexibility and support are required. It is not as rigid as bone, making it suitable for specific functions in the skeletal system.

3. **Long Bones**: One of the primary locations where cartilage is found is in long bones. Long bones are the bones that are longer than they are wide, such as the femur (thigh bone) and humerus (upper arm bone).

4. **Function of Cartilage in Long Bones**: In long bones, cartilage serves several important functions:
- It acts as a cushion between the bones, reducing friction during movement.
- It provides a smooth surface for joint movement.
- It supports the structure of the bone while allowing for flexibility.

5. **Conclusion**: Based on the understanding of where cartilage is found and its functions, we can conclude that cartilage is primarily located in long bones.

**Final Answer**: Bone cartilage is found in long bones.
