Arrange the following steps for achieving market equilibrium in a perfectly competitive market: A) Firms enter the market until profits are zero, B) The interaction of supply and demand determines the market price, C) Producers supply goods at the equilibrium price, D) Consumers demand goods at the equilibrium price.

In a perfectly competitive market, achieving market equilibrium starts with the interaction of supply and demand determining the market price. Once the price is set, consumers demand goods at this equilibrium price, which means they are willing to buy the amount that is available. At the same time, producers supply goods at this price, wanting to sell as much as they can. As firms realize profits, new firms enter the market, increasing supply until profits are driven down to zero. This process ensures that the market reaches a balance where the quantity supplied equals the quantity demanded, stabilizing the market.
