35. Phasor diagrams summarize phase and amplitude relations among passive components in AC circuits. A phasor is an arrow whose length represents the amplitude of an AC voltage or current, rotating counterclockwise with the angular frequency ω of the AC quantity. The phasor’s component on either axis represents the sinusoidally varying AC quantity. The figure shows the phasor diagram for an RLC circuit. Note that VRp is the peak value of the voltage across the resistor, VCp is the peak value of the voltage across the capacitor, and VLp is the peak value of the voltage across the inductor. About this RLC circuit, which of the following statement is correct?

(A) The driving frequency is above resonance.
(B) The driving frequency is about resonance.
(C) The driving frequency is below resonance.
(D) The driving frequency varies.
(E) The driving frequency is dominantly determined by V?p.
