Options:
  • A $120 \mathrm{~V}$
  • B $60 \mathrm{~V}$
  • C $\text { zero }$
  • D $\frac{60}{\sqrt{3}} \mathrm{~V}$

The correct answer is: $\text { zero }$
The voltage across $L$ and $C$ has phase difference of $\pi$ $\mathrm{X}=\mathrm{X}_{\mathrm{L}}-\mathrm{X}_{\mathrm{c}}=60-60=0$
Hence the resultant voltage across the combination is zero.
