Questions On Resonance in LCR Circuit||Parallel Ac Circuit

Statement-1 : A parallel resonance circuit is called a rejector circuit. statement-2 : At resonance frequency, current is completely cut off.

The parallel resonance circuit is called as

When the frequency of the AC source in an LCR circuit equals the resonant frequency, the reactance of the circuit is zero. Does it mean that there is no current through the inductor or the capacitor?
