The correct answer is: C. Natural monopoly
A natural monopoly is a market structure in which there is only one supplier of a good or service. This is because the cost of production is so high that it is not profitable for more than one company to operate in the market. Natural monopolies are often found in industries where there are significant economies of scale, such as electricity, gas, and water.
Economies of scale are cost
savings that a company can achieve by increasing the size of its production. For example, a company that produces electricity may be able to lower its costs by building a larger power plant. This is because the cost of building a power plant is largely fixed, so the company can spread the cost over a larger number of units of electricity.Natural monopolies can be beneficial to consumers because they can lead to lower prices. This is because the monopoly firm is the only supplier of the good or service, so it does not have to compete with other firms. As a result, the monopoly firm can charge a higher price than it would if there were competition. However, natural monopolies can also be harmful to consumers because they can lead to a lack of innovation. This is because the monopoly firm does not have to worry about losing customers to other firms, so it does not have to invest in new technologies or products.
Governments often regulate natural monopolies to protect consumers. For example, the government may require the monopoly firm to charge a fair price or to allow other firms to enter the market.
