Options

A. a-r , b-s, c-q, d-p
B. a-r , b-t , c-q, d-p
C. a-r, b-s, c-q, d-t
D. a-r,b-s , c-p , d-q

Answer

To solve the matching question, we will analyze each item in Column I and find its corresponding match in Column II based on their definitions and functions.

### Step-by-Step Solution:

1. **Match Cartilage (a)**:
- Cartilage is supported by a layer of connective tissue known as the **perichondrium**.
- Therefore, the match is: **a - r (Cartilage - Perichondrium)**.

2. **Match Bone (b)**:
- Bone is covered by a dense layer of connective tissue called the **periosteum**.
- Thus, the match is: **b - s (Bone - Periosteum)**.

3. **Match Muscle Fibre (c)**:
- Muscle fibers are surrounded by a specialized membrane known as the **sarcolemma**.
- Hence, the match is: **c - q (Muscle Fibre - Sarcolemma)**.

4. **Match Neuron (d)**:
- Neurons have an outer layer called the **neurilemma**, which is formed by Schwann cells.
- Therefore, the match is: **d - p (Neuron - Neurilemma)**.

### Final Matches:
- a - r (Cartilage - Perichondrium)
- b - s (Bone - Periosteum)
- c - q (Muscle Fibre - Sarcolemma)
- d - p (Neuron - Neurilemma)

### Summary of Matches:
- **A - R**
- **B - S**
- **C - Q**
- **D - P**
