Amplitudes are expressed either as instantaneous values or mostly as peak values. Amplitude is the fluctuation or displacement of a wave from its mean value. With sound waves, it is the extent to which air particles are displaced, and this amplitude of sound or sound amplitude is experienced as the loudness of sound.
In this case, Wave B would have a negative amplitude since it is a trough; and so a positive amplitude and a negative amplitude would be added together to determine the displacement of the medium at that location and moment in time.
