Question

why are utilities, such as electricity and water, examples of natural monopolies?
the cost of production restricts competition in the market.
there are limited natural resources to meet demand.
consumers only trust known companies to provide these essentials.
there is no need for alternative options.

Explanation:

Natural monopolies like utilities (electricity, water) occur because the cost of setting up infrastructure (power plants, water treatment plants, extensive distribution networks) is extremely high. If multiple firms entered the market, the average cost of production would be much higher due to duplication of infrastructure. So, the high cost of production acts as a barrier that restricts competition, making it more efficient for one firm to serve the entire market. Limited natural resources (B) is not the main reason for being a natural monopoly as these industries can manage resources (e.g., recycling water, using renewable energy for electricity). Consumer trust (C) is not the core factor; it's more about cost - efficiency. And the claim that there is no need for alternative options (D) is incorrect as in theory, alternative providers could exist but are deterred by high costs.

Answer:

A. The cost of production restricts competition in the market.
