Best answer
Right option is (a) True

The best explanation: Bode plots show the frequency response of a system. There are two Bode plots one for gain (or magnitude) and one for phase.

 The Nyquist plot combines gain and phase into one plot in the complex plane. It is drawn by plotting the complex gain g(iω) for all frequencies ω. That is, the plot is a curve in the plane parameterized by ω.
