10．已知 $f(x)$ 为偶函数，当 $x \geq 0$ 时，$f(x)=\left\{\begin{array}{c}\cos \pi x, x \in\left[0, \frac{1}{2}\right] \\ 2 x-1, x \in\left(\frac{1}{2},+\infty\right)\end{array}\right.$，则不等式 $f(x-1) \leq \frac{1}{2}$ 的解集为
A. $\left[\frac{1}{4}, \frac{2}{3}\right] \cup\left[\frac{4}{3}, \frac{7}{4}\right]$
B. $\left[-\frac{3}{4},-\frac{1}{3}\right] \cup\left[\frac{1}{4}, \frac{2}{3}\right]$
C. $\left[\frac{1}{3}, \frac{3}{4}\right] \cup\left[\frac{4}{3}, \frac{7}{4}\right]$
D. $\left[-\frac{3}{4},-\frac{1}{3}\right] \cup\left[\frac{1}{3}, \frac{3}{4}\right]$
