Explanation:

A natural monopoly occurs when economies of scale are so large that one firm can produce the entire output of the market at a lower cost than multiple firms. Pipelines, railway lines, electric companies, and fixed - line telephone companies often have high fixed costs and large economies of scale, making it inefficient to have multiple competing firms. Supermarkets and sporting goods stores do not typically exhibit these characteristics of natural monopolies.
