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

A scientific theory may be revised overtime because it goes to the loop of science which what's the scientific theory to test several times each time a different product may be shown or every now and then a different product may be shown so therefore over time as it goes through the loop of science a scientific theory may change or be revised
