Explanation
In an R-L-C circuit, the resistor consumes power, which is calculated as I²R. Both the inductor and the capacitor exchange reactive power with the supply, meaning power flows back and forth rather than being consumed. The resistor, however, does not exchange power but only dissipates it. Therefore, each statement A through D is correct, making option E the comprehensive correct choice.
