    The peak to peak of the yellow is about 4.5 divisions and the red is about 2.2. 4.5/2.2 is about 2 so (a) is the correct choice.

    [a] , gain is double than input.

    The input is ~400mv and the output is ~ 800mv so the gain is ~ 2.

    The output (green) signal appears to be around twice the amplitude of the input (red) signal.

    The only answer that fits is A for gain = 2.

    Gain = output / input.

    Gain is the ratio of the output to the input. The gain of a voltage amplifier is the ratio of the output voltage to the input voltage. I think it is negative gain.
