Voluntary muscles are found in

Options

A. alimentary canal
B. limbs
C. iris of the eye
D. bronchi of lungs

Explanation

**Step-by-Step Solution:**

1. **Understanding Muscle Tissue Types**:
- Muscle tissue can be broadly classified into three categories: skeletal muscles, smooth muscles, and cardiac muscles.

2. **Identifying Voluntary Muscles**:
- Voluntary muscles are those that are under our conscious control. This means we can decide when to move them. Skeletal muscles are the only type of muscle that falls under this category.

3. **Characteristics of Skeletal Muscles**:
- Skeletal muscles are attached to bones and are responsible for movements such as walking, running, and lifting. They are also striated, meaning they have a striped appearance when viewed under a microscope.

4. **Differentiating from Other Muscle Types**:
- Smooth muscles, found in internal organs like the digestive tract, are involuntary and not under conscious control. Cardiac muscles, found in the heart, are also involuntary but have a striated appearance.

5. **Analyzing the Options**:
- When given options, look for the one that refers to limbs or skeletal muscles, as these are the only locations where voluntary muscles are found.

6. **Conclusion**:
- Based on the analysis, voluntary muscles are found in the limbs, which allow for various movements and locomotion.

**Final Answer**: Voluntary muscles are found in the limbs.
