Answer:

D. Series LC circuit

Step-by-step explanation:

Impedance changes monotonically with frequency for an RC or RL circuit. A parallel LC circuit has a maximum of impedance at resonance. Only the series LC circuit will have its lowest impedance at resonance, and a higher impedance elsewhere in the frequency spectrum.
