If \( |\tan \mathrm{x}| \leq 1 \) and \( \mathrm{x} \in[-\pi, \pi] \) then the solution set for \( \mathrm{x} \) is
P
(a) \( \left[-\pi,-\frac{3 \pi}{2}\right] \cup\left[-\frac{\pi}{4}, \frac{\pi}{4}\right] \cup\left[\frac{3 \pi}{4}, \pi\right] \)
(b) \( \left[-\frac{\pi}{4}, \frac{\pi}{4}\right] \cup\left[\frac{3 \pi}{4}, \pi\right] \)
(c) \( \left[-\frac{\pi}{4}, \frac{\pi}{4}\right] \)
(d) none of these
