Which of the following best defines a closed loop in an electric circuit?
(a) Any continuous conducting path that contains at least one resistor, because current must pass through resistance to form a loop.
(b) A continuous conducting path that begins and ends at the same point and through which charge can flow.
(c) The collection of components wired in parallel between two common junctions, since charge can choose any branch to return.
(d) A conducting path that starts at the positive terminal of the battery and ends at the negative terminal even if the path is interrupted by an open switch.
