A. None of its zeros of its transfer function lies on the jω axis of s-plane
B. At least one zero of its transfer function lies on the jω axis of s-plane
C. None of its poles of its transfer function lies on the jω axis of s-plane
D. At least one pole of its transfer function lies on the jω axis of s-plane
Answer:D
