In a perfectly competitive market, such as the local farmers' market where Alisha and Tangguh sell their produce, what happens to prices in the long run?

• Prices stabilize at the level of minimum average total cost, resulting in zero economic profit.

• Prices increase indefinitely due to high demand.

• Prices drop below the minimum average total cost.
