Cartilage is present
a. in the tip of nose and middle ear joints
b. between adjacent bones of vertebral column
c. between adjacent bones of limbs and hands in adults

Options

A. a, b and c
B. a and b
C. b and c
D. a and c

Explanation

To determine where cartilage is present, we need to analyze the options provided:

1. **Option A**: Cartilage is present in the tip of the nose and middle ear joints.
- Cartilage is indeed found in the tip of the nose (nasal cartilage) and in the middle ear (specifically in the structures like the auricle). This option is correct.

2. **Option B**: Cartilage is present between adjacent bones of the vertebral column.
- The vertebral column has intervertebral discs made of fibrocartilage between adjacent vertebrae. This option is also correct.

3. **Option C**: Cartilage is present between adjacent bones of limbs and hands in adults.
- In adults, the long bones of limbs are connected by joints, which may have cartilage (like articular cartilage) at the ends. However, the bones themselves are not directly connected by cartilage; they are connected by ligaments and tendons. This option is not correct.

Based on the analysis:
- **Correct options are A and B**.
- **Option C is incorrect**.

### Final Answer:
Cartilage is present in:
- A. in the tip of the nose and middle ear joints (Correct)
- B. between adjacent bones of the vertebral column (Correct)
- C. between adjacent bones of limbs and hands in adults (Incorrect)
