- At resonance, the circulating current within the tank is greater than the line current.
- At resonance the line current is maximum. (Wrong since this would be for a series circuit)
- The voltage across the capacitor or coil may be higher than the applied voltage.
- At resonance the impedance of the tank is found by the formula Z = Q / XL

I've figured out that the second one is not it but struggling to be certain of the correct answer.
