An LCR circuit contains $\mathrm{R}=50\mathrm{\Omega }, \mathrm{L}=1\mathrm{mH}\text{ and }\mathrm{C}=0.1\mathrm{\mu F}\text{. }$ The impedance of the circuit will be minimum for a frequency of

• A

  $\frac{{10}^5}{2\mathrm{\pi }}{\mathrm{s}}^{-1}$

• B

  $\frac{{10}^6}{2\mathrm{\pi }}{\mathrm{s}}^{-1}$

• C

  $2\mathrm{\pi }\times {10}^5{\mathrm{s}}^{-1}$

• D

  $2\mathrm{\pi }\times {10}^6{\mathrm{s}}^{-1}$
