Answer

### Step-by-Step Solution:

1. **Identify the Question**: The question asks about the type of joint that the elbow joint represents.

2. **Review the Options**: The options provided are:
- A) Ball and socket joint
- B) Hinge joint
- C) Pivot joint
- D) Sutural joint

3. **Analyze Each Option**:
- **Option A: Ball and Socket Joint**: This type of joint allows for a wide range of motion in multiple directions. Examples include the hip joint and shoulder joint. Since the elbow does not fit this description, this option is incorrect.
- **Option B: Hinge Joint**: This type of joint allows movement in one plane, similar to the way a door opens and closes. The elbow joint connects the humerus (upper arm bone) with the radius and ulna (lower arm bones), allowing for flexion and extension. This option is correct.
- **Option C: Pivot Joint**: This joint allows for rotational movement around a single axis. An example is the joint between the first and second cervical vertebrae. The elbow does not fit this description, so this option is incorrect.
- **Option D: Sutural Joint**: These joints are immovable and found between the bones of the skull. The elbow joint does not fit this description, making this option incorrect.

4. **Conclusion**: Based on the analysis, the correct answer is **Option B: Hinge Joint**, as it accurately describes the elbow joint's function and structure.

### Final Answer:
The elbow joint is a **hinge joint**.
