Explanation:

- Option 1: Maker

A monopoly has significant control over market pricing because it is the sole provider of a product or service. Monopolists typically set prices based on potential profit maximization, acting as price makers.

- Option 2: Taker

In perfect competition, firms are price takers due to market-determined prices. This doesn’t apply to monopolies due to their control.

- Option 3: Adjuster

Adjusters refer to ability to slightly adjust to market conditions, but monopolists focus on setting the starting price.

- Option 4: None of these

Suggests none of the listed options apply, but this is incorrect for a monopolist.
