An electrical circuit is a complete path that allows electric current to flow from a power source, through conductors and components, and back to the source. This is why describing it as a path of electrical current fits best—the circuit provides the route for charge to travel. A device that stores energy, like a capacitor or battery, is a component within the circuit or a energy source, not the whole circuit itself. A measure of resistance is a property that describes how much a material opposes current, not the actual path. A resistor is a component that adds resistance, again not the circuit as a whole.
