A battery is connected to a light-bulb by two conducting wires. A single switch is placed in series with the bulb. When the switch is in the OPEN position, which of the following best describes the state of the circuit and the behavior of the bulb?
(a) Closed circuit; the bulb lights because charge can flow.
(b) Open circuit; the bulb lights briefly as charge already in the wires completes the circuit.
(c) Open circuit; the bulb remains dark because charge cannot flow.
(d) High-resistance circuit; the bulb glows dimly because a small current arcs across the open switch.
