Match the joints in column I with their examples in column II and select the correct option.
`{:("", "Column I", "", "Column III"), (A., "Hinge joint", (ii), "Neck"), (B., "Gliding joint", (ii), "Ankle"), (C., "Pivot joint", (iii), "Shoulder"), (D., "Ball and socket joint", (iv), "Elbow"):}`

Options

A. A - (iv), (B) - (ii), C - (i), D - (iii)
B. A - (iii), B - (ii), C - (i), D - (iv)
C. A - (iv), B - (i), C - (ii), D - (iii)
D. A - (ii), B - (iii), C - (iv), D - (i)

Answer

To solve the problem of matching the joints in Column I with their examples in Column II, we will analyze each joint type and its corresponding example step by step.

### Step-by-Step Solution:

1. **Identify the Hinge Joint (A)**:
- A hinge joint allows movement in one direction, similar to how a door opens and closes.
- **Example**: The elbow is a classic example of a hinge joint because it allows bending and straightening.
- **Match**: A (Hinge joint) → (iv) Elbow.

2. **Identify the Gliding Joint (B)**:
- A gliding joint allows for sliding movements between flat surfaces.
- **Example**: The ankle is an example of a gliding joint as it allows for slight movements in multiple directions.
- **Match**: B (Gliding joint) → (ii) Ankle.

3. **Identify the Pivot Joint (C)**:
- A pivot joint allows for rotational movement around a single axis.
- **Example**: The neck is an example of a pivot joint because it allows the head to rotate.
- **Match**: C (Pivot joint) → (i) Neck.

4. **Identify the Ball and Socket Joint (D)**:
- A ball and socket joint allows for a wide range of movement in multiple directions.
- **Example**: The shoulder is a classic example of a ball and socket joint, allowing for 360-degree movement.
- **Match**: D (Ball and socket joint) → (iii) Shoulder.

### Final Matching:
- A (Hinge joint) → (iv) Elbow
- B (Gliding joint) → (ii) Ankle
- C (Pivot joint) → (i) Neck
- D (Ball and socket joint) → (iii) Shoulder

### Correct Option:
- The correct matching is:
- A matches with iv
- B matches with ii
- C matches with i
- D matches with iii

Thus, the correct option is the first one.
