Q. If the damping ratio is equal to 1, a second-order system is

(A) having maginary roots of the characteristic equation
(B) underdamped
(C) critically damped with unequal roots
(D) critically damped with equal roots
Correct : Option (D)

Explanation: 
 the time response of a system with a damping ratio of 1 is critically damped. but the roots of the characteristic equation will be equal and equal to negative of the natural undamped frequency of the system.
