Which of the following statements describes the system shown in the Bode plot?

Two Bode plots are shown. The top plot displays gain in decibels versus frequency, omega. The bottom plot displays phase angle in degrees versus frequency, omega. The top plot shows the gain starting at a relatively high value at low frequencies and gradually decreasing as frequency increases. The bottom plot shows the phase angle starting at 0 degrees at low frequencies and gradually decreasing to negative 270 degrees as frequency increases. Both plots have the frequency axis labeled with points A, B, C, D, and E, indicating increasing frequency. The gain plot shows a gradual roll-off, while the phase plot shows a more rapid decrease around the frequency range of A to C.
