Answer:

  D. Series LC circuit

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.

Answer:

D. Series LC circuit

Explanation:

can be used to offer a higher impedance to all frequencies except the resonant frequency.
