Zone of no combustion
Zone of least combustion
Zone of complete combustion
Zone of incombustion

Answer 1

Explanation:

zone of complete combustion

Answer 2

Answer:

(3) complete combustion

Explanation:

combustion reaction zone

This is called the "combustion reaction zone" of the flame; it glows a delicate blue color. Sometimes, however, the fuel molecules don't burn up right away. They clump together to form particles called soot, which then swirl around inside the body of the flame without actually burning. Due to complete combustion, the outer zone is blue. This zone is the hottest in temperature when compared to the other zones. This blue coloured zone is the non-luminous part of the flame. The yellow colour region which is the bright part of the flame is the middle zone.
