这三个选项不都是表示first-degree price discrimination 吗first-degree price discrimination 就是perfect price discrimination吧

嗨，从没放弃的小努力你好：
同学你好，first-degree discrimination指的是where a monopolist can charge each customer the highest price the customer is willing to pay. This is called price discrimination because the monopolist charges a different price to each client
因此b项错误，surplus是被monopolist 得到的，而不是consumers
