The mixing depth is defined as the height of the layer in which turbulent mixing occurs and pollutants are dispersed. An unstable layer that extends from the surface up to the base of an inversion is where mixing occurs and the mixing depth can be determined. Option A describes such a layer, whereas the other options either mention stable layers or unstable layers that are above the inversion.
