Which of the following best describes aggravated assault on a disabled person?

The description of aggravated assault on a disabled person is best captured by the choice that involves intentionally inflicting serious injury on a disabled individual. This definition emphasizes the intent and the severity of the action, which are crucial components of the crime. Aggravated assault is typically characterized by the use of force that can cause significant harm and the targeting of a vulnerable individual, such as someone who is disabled. This highlights the importance of protecting those who may be at a greater risk of harm due to their circumstances.

In contrast, the other options do not accurately represent the legal definition or severity associated with aggravated assault. Using non-lethal force does not necessarily imply the intention to cause serious injury, and the mere act of threatening or making fun of a disabled person does not meet the threshold of physical assault, as they lack the component of inflicting physical harm. Therefore, the focus on deliberate injury to a disabled individual underscores the serious nature of the offense involved in aggravated assault in this context.
