Answer:
Natural monopoly
Explanation:
A natural monopoly refers to a type of monopoly that occurs when the start-up costs or infrastructural costs are high or economies of scale in an industry are very powerful in such a way that only the largest supplier in the industry which is usually the first supplier in the market has a great advantage over potential competitors and therefore becomes the only supplier in the industry.
