The root-locus plot of a closed-loop system with unity negative feedback and transfer function KG(s) in the forward path is shown in the figure. Note that K is varied from 0 to ∞.
Select the transfer function G(s) that results in the root-locus plot of the closed-loop system as shown in the figure.
A
G(s) = 1/(s + 1)5
B
G(s) = 1/(s5 + 1)
C
G(s) = (s − 1)/(s + 1)6
D
G(s) = (s + 1)/(s6 + 1)

Correct : a
