Solution

The correct option is A True
This is a resonance in the circuit--- when you have a bunch of different
frequencies driving a resonant system, the response is only strong for
those frequencies which are close to the natural frequency of the
resonant oscillator. The frequency dependent amplification is used to done through the resonance circuit for a desired frequency.
