In the series $LCR$ circuit, the voltmeter and ammeter readings are,

Which of the following options is correct?

For series $L-C-R$ $AC$ circuit shown in figure, the readings of $V_2$ and $V_3$ are same and each equal to $100 \mathrm{V}$. Then,

When an $AC$ voltage, of variable frequency is applied to series $L-C-R$ circuit, the current in the circuit is the same at $4 \mathrm{kHz}$ and $9 \mathrm{kHz}$. The current in the circuit is maximum at

An inductor $L$ and a capacitor $C$ are connected in the circuit as shown in the figure. Which ammeter will read zero ampere?

(where $\omega$ is the resonant frequency of the circuit. )
