The Nyquist plot for the open-loop transfer function \(\mathrm{G}(s)\) of a unity negative feedback system is shown below. If \(\mathrm{G}(s)\) has no pole in the right-half of \(s\) plane, the number of roots of the system characteristic equation in the right-half of \(s\)-plane is

(a) 0
(b) 1
(c) 2
(d) 3
