Which of the following is the chemical chain reaction component of the fire tetrahedron?

Explanation:
Fire needs four things to keep burning: heat, fuel, oxygen, and the chemical chain reactions that sustain the flame. The chemical chain reaction component is the set of radical reactions that propagate combustion in the flame, involving species like H, O, and OH that continually react to keep the oxidation process going. These chain reactions are the kinetic mechanism behind flame propagation, not a physical ingredient. If these radical reactions are interrupted or inhibited, the flame cannot be maintained even when heat, fuel, and oxygen are present, which is why this component is identified as the chemical chain reaction aspect of the fire tetrahedron.
