It is the hottest part of the flame, and it is where the chemical reactions that produce the flame take place. The luminous zone is white because it is made up of hot gases that are emitting light.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li><strong>Yellow<\/strong> is the color of the outer region of the flame. This region is cooler than the luminous zone, and it is where the gases that make up the flame are not as hot.<\/li>\n<li><strong>Black<\/strong> is the color of the soot that is produced when the fuel in the flame is not completely burned.<\/li>\n<li><strong>Red<\/strong> is the color of the inner region of the flame.
