The correct answer is: C. It is always beneficial for a firm in a perfectly competitive market to discriminate prices.
A perfectly competitive market is a market structure in which there are many buyers and sellers of a homogeneous good or service, and no single buyer or seller has a significant impact on the market price. In a perfectly competitive market, firms are price takers, meaning that they must accept the market price for their goods or services. This is because if a firm tries to charge a higher price, its customers will simply buy from one of the many other firms that are selling the same good or service at the lower market price.
It is not always beneficial for a firm in a perfectly competitive market to discriminate prices. Price discrimination occurs when a firm charges different prices to different buyers for the same good or service. Price discrimination can be beneficial for a firm if it allows the firm to increase its profits. However, price discrimination can also be harmful to consumers, as it can lead to higher prices for some consumers.
In a perfectly competitive market, firms are price takers, so they cannot charge different prices to different buyers. This is because if a firm tried to charge a higher price to one buyer, that buyer would simply buy from one of the many other firms that are selling the same good or service at the lower market price. Therefore, it is not always beneficial for a firm in a perfectly competitive market to discriminate prices.
