[$A$] The frequency at which the current will be in the phase with the voltage is independent of $R$.
$[B]$ At $\omega \sim 0$ the current flowing through the circuit becomes nearly zero.
[$C$] At $\omega \gg 10^6 \mathrm{rad} . \mathrm{s}^{-1}$, the circuit behave like a capacitor.
[$D$] The current will be in phase with the voltage if $\omega=10^4 \mathrm{rad} . \mathrm{s}^{-1}$
