Concept:An object or substance becomes a resource only when it has utility or usability – that is, it can serve a purpose or fulfill a human need.
Explanation:Utility is the defining factor. Without usefulness, an item remains just a material, not a resource.
Discovery alone does not make something a resource. The object must be useful to be considered a resource.
Purification can improve an object’s value, but it does not turn a useless object into a resource. The inherent utility must already exist.
Extraction is a process applied to resources after they are identified as useful. The act of extracting alone does not grant resource status.
Thus, among the given options, only utility or usability qualifies an object or substance as a resource.
Answer:C. Utility or usability
