when does a monopoly occur?\nwhen there is only one company that provides a product or service\nwhen companies that provide the same products are decentralized\nwhen one company charges very low prices for a product or service\nwhen companies producing the same product get together to set prices
Answer
Answer:
A. when there is only one company that provides a product or service
Brief Explanations:
A monopoly exists when a single - firm is the sole provider of a good or service in a market, giving it significant market power. Other options do not define a monopoly. Decentralized companies providing the same product is not a monopoly. Low - pricing by one company is not a monopoly characteristic. Companies getting together to set prices is more related to oligopoly behavior like collusion.
