Given root locus diagram is shown below,
Form above figure, at s = -1 , five root locus branches are originating following the asymptotic angles 36o,108o,180o, 252o , 324o .
Hence, there will be five poles at s = -1
Since, all the five root locus branches are terminating at infinity, hence there will be five virtual zeros i.e. no physical zero.
Therefore OLTF is given by,
Hence, the correct option is (D).
