Clinical death involves

Options

A. Stoppage of heart beat
B. Dilation of pupil
C. Absence of light reaction on pupil
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Clinical Death**: Clinical death is defined as the cessation of heartbeat and pulse. This means that the heart is no longer beating, and blood circulation has stopped.

2. **Identifying Symptoms**: In clinical death, certain physiological changes occur:
- The heartbeat stops.
- The pupils may dilate (enlarge).
- There is an absence of light reaction in the pupils (the pupils do not constrict in response to light).

3. **Distinguishing from Biological Death**: It's important to differentiate clinical death from biological death. Clinical death can occur while other organs may still function for a limited time, allowing for potential organ transplantation. In contrast, biological death refers to the death of tissues and cells, where no organs are functioning.

4. **Evaluating the Options**: The question asks what clinical death involves. The options provided are:
- Stoppage of heartbeat
- Dilation of pupil
- Absence of light reaction on pupil
- All of the above

5. **Conclusion**: Since all the symptoms listed (stoppage of heartbeat, dilation of pupil, and absence of light reaction) are associated with clinical death, the correct answer is "all of the above".

**Final Answer**: Clinical death involves all of the above.
