Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): In an impedance, Smith chart point r =0, x=0 represents open-circuit point.
Reason (R): In an impedance, Smith chart, √r = -1 and √i = 0 represents r = 0 and x = 0.
In the light of the above statements, choose the correct answer from the options given below.
