The correct answer is option 1, USA. Lake Superior, the largest freshwater lake in the world, is located primarily in the United States. It is one of the Great Lakes, which form a chain of interconnected lakes along the border of the United States and Canada. Lake Superior is mainly situated in the northeastern part of the United States, specifically in the state of Minnesota. A small portion of the lake also extends into the Upper Peninsula of Michigan. It is important to note that while Canada also shares some of the Lake Superior shoreline, the majority of the lake`s surface area falls within the United States.
