Answer:C
Which of the following statements is correct for a system with gain margin close to unity or a phase margin close to zero?
A. The system is relatively stable B. The system is highly stable C. The system is highly oscillatory D. The system is stable
Explanation: The system is highly oscillatory or unstable as the value of phase margin must be finite for the stable system.
