Question

select the best choice for the following statement.
what are the elements of a fire?
a) fuel, oxygen and ignition from a heat source
b) fuel and ignition from a fuel source
c) fuel, carbon dioxide and an oxygen source
d) fuel, oxygen, carbon dioxide and ignition from a fuel source

Explanation:

The fire triangle concept states that three elements are needed for fire: fuel (a combustible material), oxygen (to support combustion), and heat (ignition source). Option a includes these three. Option b misses oxygen. Option c has carbon dioxide (which is a product of combustion, not an element for fire). Option d has extra carbon dioxide and wrong ignition source reference.

Answer:

A. Fuel, oxygen and ignition from a heat source
