When a unit step input is applied, a second order underdamped system exhibits a peak over shoot of \(\mathrm{M}_{p}\) at \(t=t_{p}\). If another step input equal in magnitude to peak overshoot \(\mathrm{M}_{p}\) is applied at \(t=t_{p}\), then the system will settle at
(a) \(1+\mathrm{M}_{p}\)
(b) \(1-\mathrm{M}_{p}\)
(c) \(\mathrm{M}_{p}\)
(d) 1.0
