Figure shows the Nyquist plot of the open-loop transfer function \(\mathrm{G}(s) \mathrm{H}(s)\) of a system. If \(\mathrm{G}(s) \mathrm{H}(s)\) has one right-hand pole, the closed-loop system is
(a) always stable.
(b) unstable with one closed-loop right hand pole.
(c) unstable with two closed-loop right hand poles.
(d) unstable with three closed-loop right hand poles.
