Arrange the following steps in the process of effective price discrimination from the firm's perspective: A) Analyze consumer willingness to pay, B) Segment the market based on elasticity, C) Set different prices for each segment, D) Maximize profit by capturing consumer surplus.

Price discrimination is a strategy used by firms to charge different prices to different consumers based on their willingness to pay. The first step is to analyze consumer willingness to pay, which helps the firm understand how much different customers are willing to spend on a product. Next, the firm segments the market based on elasticity, meaning it identifies groups of consumers who respond differently to price changes. After segmenting the market, the firm sets different prices for each segment, allowing it to cater to various customer needs and maximize sales. Finally, by capturing consumer surplus, the firm can maximize its profit, ensuring it earns the most from each sale based on the specific characteristics of its customer segments.
