Assertion : Hinge joint is present in shoulders and hips.
Reason : Hinge joint is the joint that allows movements in all the directions.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Hinge joint is present in shoulders and hips."
- **Analysis**: Hinge joints are a type of joint that allows movement primarily in one direction (like a door). They are typically found in the elbow and knee, not in the shoulders and hips.

2. **Understanding the Reason**: The reason states that "Hinge joint is the joint that allows movements in all the directions."
- **Analysis**: This statement is incorrect. Hinge joints allow movement in one plane (flexion and extension), not in all directions. Joints that allow movement in all directions are called ball-and-socket joints, which are present in the shoulders and hips.

3. **Conclusion**:
- Since the assertion is false (hinge joints are not present in shoulders and hips) and the reason is also false (hinge joints do not allow movement in all directions), the correct answer is that both the assertion and reason are false.

### Final Answer:
Both the assertion and reason are false.
