Which example showcases an aggravated assault?

The example that showcases aggravated assault is one where an individual causes serious injury to another, as demonstrated by the scenario of knocking someone to the ground resulting in serious injury. Aggravated assault typically involves actions that go beyond simple assault, where there is intention to inflict significant harm or the use of a weapon. In this case, the act of knocking someone down and causing serious injury clearly indicates a violent confrontation that poses a threat to physical safety, which is a defining characteristic of aggravated assault.

In contrast, other scenarios listed, such as intimidation without physical contact or an argument escalating into a loud disagreement, lack the necessary element of actual harm or threat of severe injury required for aggravated assault charges. Pointing a firearm during an altercation does represent a level of threat, but unless it directly causes injury or involves further assaultive behavior, it may not meet the threshold for aggravated assault as clearly as the action resulting in serious injury does.
