Which of the following is a resonant or tuned circuit?

A resonant circuit, often referred to as a tuned circuit or an LC circuit, is fundamentally composed of an inductor (represented by 'L') and a capacitor (represented by 'C'). These components can be wired either in series or in parallel to achieve resonance. The interaction between the magnetic field of the inductor and the electric field of the capacitor causes the circuit to naturally oscillate at a specific frequency. This characteristic makes it highly sensitive to signals at its resonant frequency, allowing radios to tune into desired stations and filter out others. The distractors describe unrelated concepts. A linear voltage regulator stabilizes power supply voltage, and resistors dissipate energy as heat rather than storing and exchanging it to create resonance.
