Answer: D

Explanation: let the reflection co-efficient be expressed in terms of magnitude and direction. Magnitude is plotted as radius from the center of the chart, and the angle is measured in counter clockwise direction from the right hand side. Hence, smith chart is based on the polar pot of voltage reflection co-efficient.
