Which of these actions is allowed when using deadly force?

The option referring to preventing theft or sabotage of critical infrastructure is correct because the standing rules for the use of force allow for the use of deadly force in situations where there is a substantial threat to significant assets or lives. Protecting critical infrastructure is a priority, as it can impact national security, public safety, and the well-being of the community at large. This justification is grounded in the principle that when there is an imminent threat to vital resources, the use of force may be necessary to safeguard those assets.

In contrast, the use of deadly force in response to non-lethal threats, engaging in physical confrontations, or asserting dominance in a dispute does not meet the criteria for justification under standing rules. Non-lethal threats do not warrant such extreme measures, and actions driven by personal disputes or a desire for dominance imply a lack of immediate danger to oneself or others, thus failing to meet the seriousness required to justify the use of deadly force. These factors emphasize the need for a clear and present danger when considering the use of lethal measures.
