Which fire development stage has maximum intensity?

Explanation:
The fire reaches maximum intensity during the fully developed stage because at this point all available fuels in the compartment are involved and the heat release rate peaks. Temperatures are extremely high, flames engulf most of the room, and the airflow sustains the intense burning. Earlier stages—incipient (ignition with little flame) and growth (flames spreading and increasing)—haven’t yet reached that peak, while the decay stage involves diminishing heat as fuels are exhausted and oxygen becomes limited.
