Q1:

Assertion (A): A slight change in pole-zero configuration can cause only minor changes in root locus configuration. Reason (R): Asymptotes show the behaviour of root loci for |s| >> 1

A Both A and R are correct and R is correct explanation of A

B Both A and R are correct but R is not correct explanation of A

C A is correct but R is wrong

D R is correct but A is wrong

ANS:D - R is correct but A is wrong

Even a slight change in pole-zero position may affect root locus appreciably.
