The correct choice is (a) homogenization
Best explanation: Subcellular fragmentation is a technique that elucidates the molecular composition of an organelle. The cells are first ruptured by homogenization and as a result their membranes and internal structures get fragmented and form vesicles. Since the vesicles derived from different organelles (like ribosome, endoplasmic reticulum etc.) have different properties, they get separated from one another.
