The inductance L, Capacitance C and resistance R are the values of the components connected in series to an ac source of angular frequency $\omega$. The inductive and capacitive reactances are $X_L$ and $X_C$ respectively. If the circuit is purely resistive, then

• A

  $\mathrm{L}=\mathrm{C}$
• Correct answer
  B

  $X_L=X_C$
• C

  $\omega \mathrm{L}=\omega \mathrm{C}$
• D

  $\mathrm{R}=\mathrm{L}=\mathrm{C}$

Hence, the correct answer is option: 'B'.
