Answer

To solve the question "Which of the following is characterized by complete stoppage of heartbeat?", we will analyze the options provided and determine which one corresponds to the complete cessation of heart activity.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Cardiac Arrest**: This is a medical emergency where the heart stops beating completely, leading to a cessation of blood flow to the body. It can result in death if not treated immediately.
- **Heart Failure**: This is a condition where the heart is unable to pump effectively, but it does not mean that the heart has stopped beating entirely. The heart may still be beating, but not effectively.
- **Heart Attack**: This occurs when there is a blockage in the blood vessels supplying the heart, which can lead to damage of the heart muscle. The heart may still be beating, but it is compromised.
- **Angina Pectoris**: This is characterized by chest pain due to reduced blood flow to the heart, but it does not involve a complete stoppage of the heartbeat.

2. **Analyze Each Option**:
- **Cardiac Arrest**: This option indicates a complete stoppage of the heartbeat.
- **Heart Failure**: This indicates a reduced ability of the heart to pump blood but does not mean the heart has stopped.
- **Heart Attack**: This involves blockage but does not necessarily stop the heartbeat.
- **Angina Pectoris**: This is a symptom of pain and does not involve the heart stopping.

3. **Conclusion**:
- Based on the definitions and characteristics of each condition, **Cardiac Arrest** is the only option that is characterized by a complete stoppage of the heartbeat.

### Final Answer:
**Cardiac Arrest** is characterized by complete stoppage of heartbeat.
