What is not an option for operational resources assigned to defend structures not immediately threatened?

The correct answer focuses on the concept of proactive versus reactive strategies in fire management. Sitting and waiting for the fire to arrive does not align with effective operational resources for defending structures not immediately threatened.

Operational tactics should involve active engagement and strategies that enhance defense capabilities. Engaging in defense preparations, assessing risks and vulnerabilities, and communicating with property owners are all proactive measures. These steps aim to strengthen the defensive stance against potential fire threats, ensuring that firefighters are prepared to address risks and mitigate potential damage.

In contrast, being passive or inactive—by simply waiting for the fire to come—does not contribute to effective operational resource management. Instead, it allows for a greater risk of loss and damage, as there is no action taken to fortify the structures or make informed decisions based on the evolving situation.
