Respuesta :
The correct answer among the choices is option C. Different molecular sizes is the differences that a chromatography rely on in order to separate out parts of a solution. All chromatographic systems rely on the fact that a substance placed in contact with two immiscible phases one moving and one stationary phase will equilibriate.
Chromatography rely on to separate out parts of a solution having different molecular sizes.
How Chromatography work?
Chromatography works by passing the dissolved material through a filter material. The molecules separate into different layers when the molecules pass through the filter.
So we can conclude that Chromatography separate parts of a solution that have different molecular sizes
