Question

select the choice that best answers the following question. which of the following components is required for a fire to start? a) nitrogen b) electricity c) heat d) hydrogen

Explanation:

The fire triangle concept states that three elements are required for fire: fuel, oxygen, and heat. Heat is essential to raise the fuel to its ignition temperature. Nitrogen is not a supporter of combustion (inert in this context). Electricity is not a fundamental component (though it can provide heat as a source). Hydrogen is a fuel but not the only fuel type, and without heat, it won't combust.

Answer:

C. Heat
