all 3 are related to each other through their involvement in protein synthesis and transport.
Ribosomes are the sites of protein synthesis and carry out this work by assembling the amino acids in the appropriate sequence, as dictated by the mRNA (messenger RNA).
These cell organelles are most commonly found embedded in the endoplasmic reticulum. Large scale protein synthesis is possible due to the very large surface area offered by the endoplasmic reticulum to the ribosomes.
The main function of the endoplasmic reticulum is to transport the newly synthesized proteins over to the Golgi apparatus. The primary role of the Golgi apparatus is to modify the proteins and encase them into vesicles. From here they are transported to the various parts of the cell.
this is why it's the answer!
