In a monopolistic market structure, which of the following is most likely to create barriers to entry for potential competitors?

In a monopolistic market structure, one major barrier to entry for potential competitors is the control of resources or technology that only the monopolist possesses. This means that new businesses may struggle to find the necessary materials or innovative methods to compete effectively. For example, if a company has exclusive access to a rare mineral needed for production, no other company can easily enter that market without significant investment or finding an alternative. Additionally, monopolists may benefit from strong brand loyalty, making it hard for new entrants to attract customers. Overall, these factors create a challenging environment for new businesses trying to enter the market.
