Options

A. Wall of intestine
B. Leg muscles
C. Muscles of fore limb
D. Heart wall.

Answer

**Step-by-Step Solution:**

1. **Understanding Unstriped Muscles**: Unstriped muscles are also known as smooth muscles. They are characterized by their lack of striations (bands) when viewed under a microscope.

2. **Location of Unstriped Muscles**: Smooth muscles are primarily found in the walls of visceral organs (hollow organs) such as the intestines, blood vessels, and the bladder. They are responsible for involuntary movements within these organs.

3. **Nature of Unstriped Muscles**: Smooth muscles are involuntary, meaning they are not under conscious control. They contract slowly and rhythmically, which is essential for the functions of the organs they are part of.

4. **Analyzing the Options**:
- **Wall of Intestine**: This is a visceral organ and contains smooth muscles. Therefore, this option is correct.
- **Leg Muscles**: These are skeletal muscles, which are striped and under voluntary control. This option is incorrect.
- **Muscles of Forelimb**: Similar to leg muscles, forelimb muscles are also skeletal muscles and are striped. This option is incorrect.
- **Heart Wall**: The heart wall is made up of cardiac muscles, which are also striped. This option is incorrect.

5. **Conclusion**: Based on the analysis, the correct answer is that unstriped muscles are present in the wall of the intestine.

**Final Answer**: Unstriped muscles are present in the wall of the intestine.
