The root locus plot for a system is given below. The open loop transfer function corresponding to this plot is given by

Which of the following points is NOT on the root locus of a system with the open loop transfer function $$$G\left(s\right)H\left(s\right)=\frac K{s(s+1)(s+3)}$$$

Given the $$G\left(s\right)H\left(s\right)=\frac K{s\left(s+1\right)\left(s+3\right)}$$, the point of intersection of the asymptotes of the root loci with the real axis is

The root-locus diagram for a closed loop feedback system is shown in Figure. The system is overdamped.
