<span>This result is produced by the selective permeability of the plasma membrane when the presence of negatively charged ions does not diffuse into the cell and the action of several sodium-potassium pump units causes an unequal distribution of charges through the membrane.</span>

Hi, it has to be a.):
The ribosomes are RNA-protein complexes that carry out the protein synthesis in cells
The rough endoplasmis reticulum is covered with ribosomes, which produce membrane proteins and proteins for secretion. The smooth ER is involved in the production of lipids, such as phospholipids for the membranes.
In the Golgi apparatus, the proteins get posttranslationally modificated by adding oligosaccharides to them(glycosylation), this oligosaccharides get assembled there, so this probably counts as producing new molecules
