Which row correctly lists all three standard restricted domains used to
define $\arcsin$ , $\arccos$ , and $\arctan$ ?

$\arcsin$ : $\left[-\tfrac{\pi}{2}, \tfrac{\pi}{2}\right]$ ;
$\arccos$ : $[0, \pi]$ ;
$\arctan$ : $\left(-\tfrac{\pi}{2}, \tfrac{\pi}{2}\right)$

$\arcsin$ : $[0, \pi]$ ;
$\arccos$ : $\left[-\tfrac{\pi}{2}, \tfrac{\pi}{2}\right]$ ;
$\arctan$ : $\left(-\tfrac{\pi}{2}, \tfrac{\pi}{2}\right)$

$\arcsin$ : $\left[-\tfrac{\pi}{2}, \tfrac{\pi}{2}\right]$ ;
$\arccos$ : $\left[-\tfrac{\pi}{2}, \tfrac{\pi}{2}\right]$ ;
$\arctan$ : $(0, \pi)$

$\arcsin$ : $[-1, 1]$ ;
$\arccos$ : $[-1, 1]$ ;
$\arctan$ : $(-\infty, \infty)$
