问题如下：
The primary difference between P/E multiples based on comparables and P/E multiples based on fundamentals is that fundamentals-based P/Es take into account:
选项：
A.future expectations.
B.the law of one price.
C.historical information.
解释：
A is correct.
Multiples based on comparables are grounded in the law of one price and take into account historical multiple values. In contrast, P/E multiples based on fundamentals can be based on the Gordon growth model, which takes into account future expected dividends.
比较的那种跟一价定律和历史信息为什么相关呀？
