(Please hurry; 100 points) What is the relationship between ribosomes and rough endoplasmic reticulum (ER)?

Rough ER produces the polypeptide chains that ribosomes need to make protein.
Rough ER is the subunit of ribosomes that makes proteins
Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell
Ribosomes transport proteins made by rough ER to the Golgi apparatus.
