Answer 2

Explanation:

The different zones of a candle flame can be described as follows:

1. The innermost zone: The innermost zone is the zone which is formed just around the wick of the candle flame as the candle burns
2. Middle zone: The middle zone also known as luminous zone is the zone which is moderately hot with limited oxygen supply.
3. The outermost zone: The outermost zone also known as non-luminous zone is the zone of complete combustion. The ample presence of oxygen (or air) aids in complete combustion. It is the hottest zone of the candle flame and does not produce much light. It is blue in colour.
