B) multiplying the resistance and the inductance
C) multiplying the voltage and the current
D) the ratio of the resistance to the inductance

The exact amount of phase angle difference between voltage and current in an AC circuit with resistance and inductance is determined by the ratio of the resistance to the inductance. This is because the phase angle is determined by the relationship between the voltage and the current, which in turn is influenced by the ratio of resistance (which opposes the flow of current) to inductance (which resists changes in current flow).
