What action by Janice exemplifies assault inflicting serious injury?

Choosing the action of stabbing Betty with a knife during an altercation exemplifies assault inflicting serious injury because it involves the use of a weapon that can cause significant physical harm. Assault inflicting serious injury generally refers to acts that result in serious bodily injury to another person, and stabbing is an act that intentionally causes serious harm or poses a significant risk of serious injury.

This action goes beyond mere verbal altercations or non-threatening physical interactions. In contrast, calling someone insulting names does not cause physical harm, pushing someone to the ground accidentally does not indicate intentional harm, and throwing a glass, while potentially harmful, may not necessarily meet the legal standard for serious injury depending on the circumstances and outcome. The key element here is the intention to cause harm and the potential for serious injury, making the stabbing the clearest example of assault inflicting serious injury.
