The correct answer is deadly force, which is defined as force that is likely to result in serious injury or death. This type of force is employed in situations where there is an imminent threat to life or severe bodily harm, and no other reasonable alternatives exist to address the threat.

In the context of security training, understanding when deadly force is appropriate and the legal implications surrounding its use is critical. It's essential for security personnel to differentiate between the levels of force they may utilize, particularly in high-stress situations. Employing deadly force comes with significant responsibility; thus, the circumstances justifying its use must be carefully assessed to ensure that it is necessary and proportionate in response to the threat faced.

Other forms of force, such as excessive force, reasonable force, or unreasonable force, do not inherently carry the same level of risk for causing fatal outcomes, which is why they do not fit the description of potentially lethal force in the same manner as deadly force does.
