A negative feedback system has loop transfer function \(K(s+3) /(s+8)^{2}\) where \(K\) is be adjusted that the system exhibits sustained oscillation. The corresponding frequency of oscillation, is
(a) \(4 / \sqrt{3} \mathrm{rad} / \mathrm{sec}\).
(b) \(4 \mathrm{rad} / \mathrm{sec}\).
(c) \(4 \sqrt{3} \mathrm{rad} / \mathrm{sec}\).
(d) No such K exists.
