(A) Low voltage output

(B) Low frequency output

(C) Distortion loss output

(D) Noiseless output

non of your answers is correct.

It provides 120 VAC at 60 Hz at a significant power level (240/50 in europe).

A plain oscillator can be anywhere in the range of 0.01 Hz to the GHz range. Usually the voltage and power level is low compared to an inverter. Most oscillators have lower distortion than an inverter.

(D) Noiseless output
