Question

price discrimination

○ can maximize profits if the seller can prevent the resale of goods between
customers.

○ is illogical because it does not maximize profits.

○ can occur in both perfectly competitive and monopoly markets.

○ is illegal in the united states and europe.

Explanation:

1. Analyze the first option: Price discrimination (charging different prices to different customers) can maximize profits when the seller can prevent resale (so customers can't buy at a lower price and resell at a higher one, undermining the price differences).
2. Analyze the second option: Price discrimination is a way to maximize profits (by capturing more consumer surplus), so this is incorrect.
3. Analyze the third option: Perfectly competitive markets have many firms with identical products, so price discrimination isn't possible (firms are price takers). It's more common in monopoly or monopolistic competition, so this is incorrect.
4. Analyze the fourth option: Price discrimination isn't illegal in general in the US and Europe; there are legal forms (e.g., student discounts, senior discounts), so this is incorrect.

Answer:

A. can maximize profits if the seller can prevent the resale of goods between customers.
