B. heart are involuntary and unstriated smooth muscles.
C. intestine are striated and involuntary
D. thigh are striated and voluntary

Answer

**Step-by-Step Solution:**

1. **Identify the Types of Muscles**: There are three main types of muscle tissue in the human body: skeletal muscle, cardiac muscle, and smooth muscle. Each has distinct characteristics and functions.

2. **Analyze the Options**:
- **Upper Arm**: The muscle type in the upper arm is skeletal muscle, which is striated and voluntary, not smooth muscle.
- **Heart**: The heart contains cardiac muscle, which is involuntary and striated, not smooth muscle.
- **Intestine**: The muscles in the intestine are smooth muscle, which is involuntary and unstriated, not striated.
- **Thigh**: The thigh muscles are skeletal muscle, which is striated and voluntary.

3. **Determine the Correct Answer**: Based on the analysis, the correct answer is that the muscles present in the thighs are striated and voluntary.

4. **Justification**: Skeletal muscles are responsible for moving bones and supporting the skeleton. They are called striated muscles due to their appearance, which is caused by the arrangement of actin and myosin filaments forming sarcomeres within myofibrils.

5. **Conclusion**: Therefore, the type of muscle present in our thighs is striated and voluntary.
