An individual muscle fibre is wrapped by :

Options

A. A) sacromeres
B. B) endomysium
C. C) perimysium
D. D) epimysium

Explanation

To solve the question "An individual muscle fibre is wrapped by:", we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Muscle Structure**:
- Muscle fibers are the basic units of muscle tissue. Each muscle is made up of bundles of these fibers.

2. **Identifying the Layers of Muscle**:
- Muscles have different layers of connective tissue that wrap around them. The main layers are:
- **Epimysium**: The outermost layer that surrounds the entire muscle.
- **Perimysium**: The layer that surrounds bundles of muscle fibers called fascicles.
- **Endomysium**: The innermost layer that surrounds individual muscle fibers.

3. **Focusing on the Question**:
- The question specifically asks about the wrapping around an individual muscle fiber.

4. **Selecting the Correct Option**:
- From the options provided:
- A. Saccharomyces (not relevant)
- B. Endomysium (correct answer)
- C. Perimysium (surrounds fascicles, not individual fibers)
- D. Epimysium (surrounds the entire muscle, not individual fibers)
- The correct answer is **B. Endomysium**.

### Final Answer:
An individual muscle fibre is wrapped by **Endomysium** (Option B).
