Question: The open-loop transfer function of a unity feedback control system is given by (mathrm{G}(s)=frac{mathrm{K}}{s(s+1)}). If the gain (mathrm{K}) is increased to infinity, then the damping

The open-loop transfer function of a unity feedback control system is given by \(\mathrm{G}(s)=\frac{\mathrm{K}}{s(s+1)}\). If the gain \(\mathrm{K}\) is increased to infinity, then the damping ratio will tend to become:
(a) \(\frac{1}{\sqrt{2}}\)
(b) 1
(c) 0
\((d) \infty\)
