The fire will die when....

B) The rate of heat generation is equal to the heat loss
C) The rate of heat generation is less than the heat loss
D) All the above
C) The rate of heat generation is less than the heat loss
Explanation
For a fire to sustain itself, it needs fuel, oxygen, and enough heat to keep the combustion process going. If the fire loses heat more rapidly than it can generate it, it won't be able to maintain the temperature necessary for combustion to continue. This leads to the fire dying out. Therefore, the scenario where the rate of heat generation is less than the heat loss directly leads to the fire's extinction, as it signifies the fire's inability to sustain the energy required for combustion.
