Sarcolemma is found over

Options

A. Nnerve fibre
B. areolar tissue
C. bone marrow cavity
D. skeletal muscle fibre

Answer

### Step-by-Step Solution:

1. **Understanding Sarcolemma**: Sarcolemma is a specialized type of cell membrane. It is important to identify where it is found in the body.

2. **Identifying Options**: The options given are:
- Nerve fibres
- Areolar tissue
- Bone marrow cavity
- Skeletal muscle fibres

3. **Analyzing Each Option**:
- **Nerve fibres**: These have a different type of membrane called the myelin sheath, not sarcolemma.
- **Areolar tissue**: This is a type of connective tissue and does not have sarcolemma.
- **Bone marrow cavity**: This is involved in blood cell production and does not contain sarcolemma.
- **Skeletal muscle fibres**: These are striated muscle cells that have a sarcolemma.

4. **Conclusion**: Based on the analysis, sarcolemma is specifically found over skeletal muscle fibres.

5. **Final Answer**: The correct answer is **option 4: skeletal muscle fibres**.
