A particular parallel \(R L C\) circuit has the step response observed on an oscilloscope and shown in Figure P7-62. Four points on the waveform were measured and are shown.

Determine the circuit's initial value, final value, the dominant exponential's time constant, and the likely case ( \(\mathrm{A}, \mathrm{B}\), or \(\mathrm{C}\) ) of the circuit response.
