Q.) Constant N-loci:

(A) constant gain and constant phase shift loci of the closed-loop system.

(B) plot of loop gain with the variation in frequency

(D) circles of constant phase shift for the closed loop transfer function

Correct answer : Option (C) - circles of constant gain for the closed loop transfer function

Explanation:

 constant n loci are the circles of constant gain for the closed loop transfer function and the intersection point of the m and n is always the point (-1,0).
