-The correct answer is B.
-The root locus plots the poles of the closed loop transfer function in the complex s-plane as a function of a gain parameter (see pole–zero plot). A graphical method that uses a special protractor called a "Spirule" was once used to determine angles and draw the root loci.
-The root locus procedure should produce a graph of where the poles of the system are for all values of gain K. When any or all of the roots of D are in the unstable region, the system is unstable. When any of the roots are in the marginally stable region, the system is marginally stable (oscillatory).

Consider the following statements: In root-locus plot, the breakaway p...
The statement 2 is correct. Breakaway points in a root-locus plot always lie on the root loci.

The statement 1 is incorrect. Breakaway points in a root-locus plot can be on the real axis, but they can also be complex conjugate pairs off the real axis.

The statement 4 is incomplete. It seems to be cut off, so it is not possible to determine its accuracy.
