In which zone of a candle flame does no combustion take place?

Options

A. Innermost zone
B. Middle zone
C. Outermost zone
D. There is no such zone in a candle flame

Answer

**Step-by-Step Solution:**

1. **Understanding Candle Flame Zones:**
A candle flame consists of three distinct zones: the innermost zone, the middle zone, and the outermost zone. Each zone has different combustion characteristics.

2. **Identifying the Innermost Zone:**
The innermost zone of the candle flame is where no combustion occurs. This is because there is a lack of oxygen supply in this area.

3. **Reason for No Combustion:**
Since combustion requires oxygen, the absence of oxygen in the innermost zone means that no combustion can take place there. Therefore, this zone is characterized by the absence of flame and combustion reactions.

4. **Analyzing Other Zones:**
- The **middle zone** experiences incomplete combustion due to limited oxygen supply.
- The **outermost zone** has complete combustion because it has an ample supply of oxygen.

5. **Conclusion:**
Based on the analysis, the correct answer to the question "In which zone of a candle flame does no combustion take place?" is the innermost zone.

**Final Answer:**
The innermost zone of a candle flame is the zone where no combustion takes place.
