Q. The addition of open loop zero pulls the root loci towards:

(A) the left and therefore system becomes more stable
(B) the right and therefore system becomes unstable
(C) imaginary axis and therefore system becomes marginally stable
(D) the left and therefore system becomes unstable

Explanation by: Mr. Dubey 
 the system can become stable by reducing the damping and also by adding zeroes in the s plane and moving left of the s plane system becomes more stable.
