The given block diagram for the feedback system is shown below.The loop-transfer function is.The given Bode plot is shown below,Note: Since no method is specified in the question, so we will use MATLAB to find gain margin and phase margin.MATLAB code is shown below.1num = [1]; 2den = [1 2 2.2 0.2]; 3sys = tf(num,den); 4margin(sys)MATLAB output is shown below.From the above result we can see that the phase margin is.From the above result we can see that the gain margin is dB.But we need to find the gain margin (not in dB). dB.So the gain margin is and in dB the gain margin is dB. Hence option (a) matches with our answers.The correct answer is option (a) Gain Margin: , Phase Margin: .
