Where is Lake Superior, the largest freshwater lake in the world, located?

Lake Superior is the world's largest freshwater lake by surface area, covering approximately 31,700 square miles [c1, t7]. It is one of the five Laurentian Great Lakes of North America and is situated on the international border between the United States and Canada [t2, t3]. Specifically, the lake's shoreline is shared by the Canadian province of Ontario and the U.S. states of Minnesota, Wisconsin, and Michigan [t1, t6]. While it straddles both nations, in the context of standard competitive examinations like the UPSC, it is primarily associated with the North American Great Lakes system shared by the USA and Canada. Since the question asks for a single location and lists both USA and Canada as separate options, it is technically a shared resource [t2]. However, the majority of its southern and western shorelines belong to the USA [t1, t9]. Given the options, USA is a primary stakeholder, though the lake is geographically binational.
