If an open occurs at R1, the light

Explanation:
When R1 opens, the intended path that the control circuit uses to supply and interrupt current to the light is broken. That can leave the light fed by a different path that the switch cannot interrupt, so the lamp remains energized regardless of the control input. In this setup, the open effectively prevents the switch from turning the light off, so the light cannot be turned off. If there were no alternate path, the lamp simply would not light, but with the fault present, the switch loses control and the lamp stays on until power is removed or the fault is fixed.
