问题如下：
Which of the following is not a result of arbitrage?
选项：
A.Convergence of prices.
B.Market efficiency.
C.The law of similar prices.
解释：
C is correct. Arbitrage forces the prices to converge, thus market efficiency improves. The law of one price is the result of arbitrage, not the law of similar prices.
中文解析：
套利迫使价格趋同，从而提高了市场效率。A和B的表述是对的。
law of one prices是套利的结果，而不是law of similar prices。C表述错误
题干要去选错误的表述，选C
the law of one price,我觉得是arbitrage产生得原因，有一价律，才可以导致套利，不是吗？能否解释一下套利导致一价律背后得原理？
