The input-output transfer function of a plant \(\mathrm{H}(s)=\frac{100}{s(s+10)^{2}}\). The plant is placed in a unity negative feedback configuration as shown in the figure below.

The gain margin of the system under closed loop unity negative feedback is
(a) \(0 \mathrm{~dB}\)
(b) \(20 \mathrm{~dB}\)
(c) \(26 \mathrm{~dB}\)
(d) \(46 \mathrm{~dB}\).
