A system has poles at \(0.01 \mathrm{~Hz}, 1 \mathrm{~Hz}\) and \(80 \mathrm{~Hz}\); zeros at \(5 \mathrm{~Hz}, 100 \mathrm{~Hz}\) and \(200 \mathrm{~Hz}\). The approximate phase of the system response at \(20 \mathrm{~Hz}\) is
(a) \(-90^{\circ}\)
(b) \(0^{\circ}\)
(c) \(90^{\circ}\)
(d) \(-180^{\circ}\)
