Which of the following is a component of the fire tetrahedron that relates to the energy input to start combustion?

Explanation:
Heat is the energy input that starts combustion. It raises the temperature to the ignition point, providing the activation energy needed to break bonds and begin rapid oxidation. Fuel and oxygen are the materials that react, while the chemical chain reaction describes the series of radical steps that keep the flame going once ignition has occurred. Without enough heat, the mixture won’t reach ignition and the flame won’t start, even if fuel and oxygen are present.
