Which statement correctly identifies R1?

Explanation:
R1 identifies the resistance of the first component—the opposition that this component offers to current flow. It is a property of that specific part, measured in ohms, and is defined by the component itself. It is not the total resistance of the entire circuit, nor the component’s power rating (that’s in watts), and it’s not the voltage drop across the component. The voltage drop across this component depends on both the current through it and its resistance, via V = I × R. So R1 is best understood as the resistance of the first component, determining how much it resists current.
