Integrate the rational functions $\frac{\cos x}{(1-\sin x)(2-\sin x)}\qquad[Hint:Put\;\sin x=t]$

Question

$\begin{array}{1 1} \log\large \frac{|1-sin x|}{|2-sin x|}+c \\\log\large \frac{|2-sin x|}{|1-sin x|}+c \\\log\large \frac{|1+sin x|}{|2-sin x|}+c \\ \log\large \frac{|1-sin x|}{|2+sin x|}+c \end{array} $
