Solution

The correct option is D R. F. oscillator.
An RF oscillator produces signals of radio frequency range of about 100KHZ to 100GHZ . It is designed to produce a high powered AC output . In an RF oscillator's combinations of resistor , capacitor and Inductor is used .In A.M modulation the frequency of carrier wave is set by R.F oscillator.
