Solution

The correct option is C may be more than 110 V across L or C but must be less than 110 V across R.
RMS value of voltage source
Vs = 110 volts
Vs=VR2+(VLVC)2
where VR,VL, VC is voltage across resistance, inductor and capacitor.
From above formula it's obvious that VR or (VLVC) can't be larger than Vs.
So, difference of VL & VL should less than Vs(110V).
But individual value of VL and VC may be grater than 110 volts.
So, D is correct answer.
