A perfect competitor would

A) never charge above market price but might charge below market price.
B) never charge below market price but might charge above market price.
C) always charge market price.

A perfect competitor is a theoretical concept in which the market is composed of many small firms that all produce identical products, and no individual firm has any control over the market price. Therefore, a perfect competitor would always charge the market price since they cannot influence it. The other options imply that the firm has some sort of market power, which would disqualify them from being a perfect competitor.
