Solution

The correct option is A positive feedback

An oscillator is an electronic circuit that converts DC from a power supply to an AC signal. An oscillator produces a periodic and oscillating signal. An oscillator is like an amplifier that gives positive feedback to the circuit. Positive feedback means that a portion of output is combined in phase with the input.
