What qualifies as a "Deadly weapon"?

A "deadly weapon" is defined primarily as a firearm or any item that is designed specifically to inflict death or serious bodily harm. This definition encompasses a variety of objects, including typical weapons like guns or knives, as well as other items that, while not designed solely for inflicting harm, can do so effectively in certain circumstances.

This definition emphasizes the inherent purpose and potential of the item to cause significant injury or fatality, rather than how it is used or its accessibility. In contrast, the other options lack this specific emphasis. While self-defense (the first option) and criminal use (the fourth option) may involve deadly weapons, they do not define the characteristics that categorize an object as a deadly weapon. The third option regarding the ease of obtaining a weapon does not pertain to its classification as deadly either. Hence, the most accurate definition is the one that focuses on the intended design and capacity to cause severe harm or death.
