问题如下：
Peter collects the following information from three companies in the same industries,Which of the companies is most likely to be undervalued?
选项：
A.B
B.A
C.C
解释：
C is correct.
Relative to the others, C has the lowest P/E multiple and the P/B multiple is tied for the lowest with B. Given the law of one price, similar companies should trade at similar P/B and P/E levels. Thus, based on the information presented, C is most likely to be undervalued.
考点：Price Multiple Approach
处在相同行业的三家可比公司即规模、行业、发展情况差不多的三家公司，根据一价定律他们的交易价格应该相似，通过相对估值法我们看到C的PE\PB都是最低的，说明他的价格被低估了。
老师，请以此题为例，讲一下什么是一价定律，李老师在视频里一句话带过，根本没讲明白。此题三个公司从什么角度来比较被高估还是被低估啊？
