    d) 2

    The input (red signal) has a peak value of 240 mV ( 2.4 divisions x 100 mV per division)

    The output (yellow signal) has a peak value of 480 mV ( 2.4 divisions x 200 mV per division)

      The red signal overlaps the yellow signal, if you look carefully

    It appears the signals are superimposed, but the scope gain is twice as high for the input signal. (100 mV/div vs 200 mV/div). So Av = 2. Answer d.
