Based on the chart and schematic, between which two points is there an open circuit (with measurements referenced to E)?

Explanation:
Open circuit means there’s a break in the conducting path so no current can flow between two points that would normally be connected. In the diagram, the segment between the two points is interrupted, creating no path for current to travel when referencing measurements to E. With an open between those points, the impedance is effectively infinite, so the two sides can float to different voltages relative to the reference E. The other pairs show a continuous connection, so they’re not open circuits. Therefore, the two points with a broken connection are the open-circuit pair.
