In scenario B, as presented here, only the line count mattered as that was the only detail present. A and B were in fact the same regards resolution. Pretty obvious that angle, contrast, and color channel had no bearing on resolution in that example.

The limit to resolution at visible contrast levels in these samples is the sampling rate; IOW, the same maximum resolution, but at different contrast levels.  Things are quite different when the optics are over-sampled for usable contrast levels.  Then, resolution is limited in a practical sense by usable contrast in the face of noise.
