A.increase its price. B.make an economic profit. C.face a demand that is more elastic.解释：
A firm in a monopolistic competition that introduces a new and differentiated product is able to better differentiate its products, and thus demand would be less elastic as close substitutes would be less readily available.

中文解析：
在垄断竞争中，如果一家公司推出了一种新的差异化产品，那么它就能够更好地区分自己的产品，因此需求的弹性就会降低，因为接近的替代品不太容易获得。这样，企业就可以提高价格，并在短期内获得经济利润。
垄断竞争的需求曲线就是平坦地向下倾斜，弹性较大啊，为什么是错的
