When the Service Disconnect Junction Box (SBJ) is removed from the panel, the circuit effectively becomes open at that point, which interrupts the flow of electrical current. In this scenario, if you measure the voltage between points B and C with a meter, the absence of continuity means that there is no potential difference between those points since they are no longer connected through the closed circuit.

This results in the voltmeter reading 0 volts because an open circuit cannot provide any voltage. The other answer choices involve values that suggest a closed circuit or connections have been maintained, which is not the case here. Therefore, the correct reading in this situation is indeed 0 volts, confirming that there is no electrical potential difference present when the junction box is removed.
