Which of the following could be a situation for using non-deadly force?

Using non-deadly force is often justified in situations where there is an immediate threat that does not require lethal response but still necessitates some level of control to maintain order or mission integrity. In the context of a perceived threat to mission objectives, the application of non-deadly force may be appropriate to de-escalate the situation, assert control, or prevent potential harm without resorting to lethal measures.

In contrast, acts of vandalism in a restricted area might necessitate intervention, but the nature of the response would depend on the specific circumstances, and it may not directly imply a need for non-deadly force. A challenge to authority by a subordinate could also potentially be addressed without force, focusing more on communication and disciplinary measures rather than escalating to physical force. A military inspection typically involves adherence to protocols and standards and is generally a non-confrontational scenario, making the use of force, whether deadly or non-deadly, less applicable.
