Consider the following statement:
A. A system is said to be stable if its output is bounded for any input
B. A system is said to be stable if all the roots of the characteristic equation lie on the left half of the s plane.
C. A system is said to be stable if all the roots of the characteristic equation have negative real parts.
D. A second order system is always stable for finite values of open loop gain
Answer:A
