While doing work and running, you move your organs like hands, legs, etc.
Which among the following is correct?

Options

A. Smooth muscles contract and pull the ligament to move the bones
B. Smooth muscles contract and pull the tendons to move the bones
C. Skeletal muscles contract and pull the ligament to move the bones
D. Skeletal muscles contract and pull the tendon to move the bones

Explanation

To solve the question regarding the movement of organs like hands and legs while doing work and running, we need to analyze the options provided and understand the role of different types of muscles and connective tissues in the body.

### Step-by-Step Solution:

1. **Understanding Muscle Types**:
- There are three types of muscles in the human body: skeletal, smooth, and cardiac muscles. Skeletal muscles are responsible for voluntary movements, which means we can control them consciously.

2. **Identifying the Role of Skeletal Muscles**:
- Skeletal muscles contract to produce movement. When these muscles contract, they exert force on the tendons.

3. **Role of Tendons**:
- Tendons are connective tissues that attach muscles to bones. When a skeletal muscle contracts, it pulls on the tendon, which in turn pulls on the bone, causing movement.

4. **Analyzing the Options**:
- **Option 1**: Smooth muscles contract and pull the ligament to move the bones. (Incorrect, as smooth muscles are involuntary and do not directly move bones.)
- **Option 2**: Smooth muscles contract and pull the tendons to move the bones. (Incorrect for the same reason as above.)
- **Option 3**: Skeletal muscles contract and pull the bones. (Partially correct, but it does not mention tendons.)
- **Option 4**: Skeletal muscles contract and pull the tendons to move the bones. (Correct, as it accurately describes the process.)

5. **Conclusion**:
- The correct answer is **Option 4**: Skeletal muscles contract and pull the tendons to move the bones.
