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:

A natural monopoly occurs when a single firm can supply a good or service to an entire market at a lower cost than could two or more firms. For utilities like electricity and water, the cost of production (e.g., building and maintaining infrastructure like power grids or water pipelines) is so high that having multiple competitors would lead to higher overall costs (due to redundant infrastructure). This high production cost restricts competition, making it a natural monopoly. The other options are incorrect: limited natural resources aren't the main reason (utilities are about distribution/ production infrastructure), consumer trust in known companies is not the definition of a natural monopoly, and the "no need for alternative options" is not the economic reason for natural monopolies.

Answer:

A. The cost of production restricts competition in the market
