Options

A. Middle zone
B. Innermost zone
C. Outernost 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 inner zone, the middle zone, and the outer zone. Each zone has different characteristics regarding combustion.

2. **Identifying the Zones**:
- **Inner Zone**: This is the part closest to the wick. It is characterized by a lack of oxygen, which means that combustion does not occur here.
- **Middle Zone**: This zone experiences incomplete combustion due to a limited supply of oxygen.
- **Outer Zone**: This is the outermost part of the flame where complete combustion occurs because there is sufficient oxygen available.

3. **Determining the Zone with No Combustion**: Among the three zones, the inner zone is the only area where no combustion takes place due to the absence of oxygen.

4. **Conclusion**: Therefore, the zone of a candle flame where no combustion takes place is the **inner zone**.

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