Given Fig. 18.35 shown a flexible shaft of negligible mass of torsional stiffness \(K\) coupled to a viscous damper having a coefficient of viscous damping \(c\). If at any instant the left and right ends of this shaft have angular displacement \(\theta_{1}\) and \(\theta_{2}\) respectively, then the transfer function, \(\theta_{2} / \theta_{1}\) of the system is

(a) \(\frac{K}{K+c}\)
(b) \(\frac{1}{1+\frac{C}{K} s}\)
(c) \(\frac{1}{1+\frac{K}{c} s}\)
(d) \(1+\frac{K}{c} s\)
