问题如下：
The price of a stock at t = 0 is $208.25 and at t = 1 is $186.75. The continuously compounded rate ofreturn for the stock from t = 0 to t = 1 is closest to:
选项：
A.–10.90% B.–10.32% C.11.51%解释：
The continuously compounded return from t = 0 to t = 1 is r0,1 = ln(S1/S0) = ln(186.75/208.25) = –0.10897 = –10.90%.
我为什么怎么算都是b？ 我用186.75=208.25（1+x）算出来是选项b
或者我用186.75-208.25/186.75算出来怎么也是选项b？哪里出了问题
