The forward-path open-loop transfer function of a unity

The forward-path open-loop transfer function of a unity feedback system is
G(s) = K(s² + 4)
(s² + 1)

For this system root locus is

In this option, locus start from poles and end on origin. In (c) and (d) poles and zero are marked incorrect.

G(s) =	K(s² + 4)
	(s² + 1)
