Q. The range of the controller gains (

K_{p}, K_{i}

) that makes the closed loop control system (shown in the following figure) stable is given as

$K_{i} < 0 a n d K_{p} < \frac{K_{i}}{12} - 20$
$K_{i} > 0 a n d K_{p} > 0$
$K_{i} < 0 a n d K_{p} > \frac{K_{i}}{12} - 20$
$K_{i} > 0 a n d K_{p} > \frac{K_{i}}{12} - 20$
