In legal terminology, which option best describes an object that is considered a "deadly weapon"?

The definition of a "deadly weapon" in legal terminology focuses on an object's capability to cause death or serious injury. This understanding is rooted in the law, which emphasizes the potential of an object to inflict significant harm rather than its intended purpose or design.

For example, tools or items that are not inherently meant for harm can still be categorized as deadly weapons if they are used in a manner that threatens life or safety. The legal perspective recognizes the context in which an object is used, highlighting that the capacity to inflict serious injuries plays a crucial role in defining what constitutes a deadly weapon.

Objects that are merely decorative, can cause mild injury, or are intended for self-defense do not meet the criteria set by the legal definition. The focus is strictly on the potential lethality or serious injury capability of the item in question, making the fourth option the most accurate and relevant in the context of legal discussions on deadly weapons.
