C
The inductance and capacitance in the tank circuit
D
The time delay of the lag circuit
Answer Notes
An LC oscillator relies on a resonant circuit, commonly known as a "tank circuit," to establish and maintain its operating frequency. The "L" stands for inductance (provided by a coil) and the "C" stands for capacitance (provided by a capacitor).
The resonant frequency of this tank circuit is strictly determined by the physical values of these two components. Energy oscillates back and forth between the magnetic field of the inductor and the electric field of the capacitor, creating a natural frequency of oscillation.
Distractors mentioning counters, dividers, or lag circuits are describing components of modern digital synthesizers or phase-locked loops, not the fundamental analog LC oscillator.
