The Nyquist stability criterion and the Routh criterion both are powerful analysis tools for determining the stability of feedback controllers. Identify which of the following statements is FALSE.

[GATE EC 2018]

A Both the criteria provide information relative to the stable gain range of the system.

B The general shape of the Nyquist plot is readily obtained from the Bode magnitude plot for all minimum-phase systems.

C The Routh criterion is not applicable in the condition of transport lag, which can be readily handled by the Nyquist criterion.

D The closed-loop frequency response for a unity feedback system cannot be obtained from the Nyquist plot.
