How does an impedance-matching circuit transform a complex impedance to a resistive impedance?

1. AIt introduces negative resistance to cancel the resistive part of impedance
2. BIt introduces transconductance to cancel the reactive part of impedance
3. CIt cancels the reactive part of the impedance and changes the resistive part to the desired value
4. DReactive currents are dissipated in matched resistances
