The correct option is B Rough endoplasmic reticulum
The nuclear membrane is in connection with rough endoplasmic reticulum. They are both parts of the endomembrane system. When a cell makes proteins, it starts by transcribing RNA from the DNA located inside its nucleus. RNA is then carried out of the nucleus into the rough endoplasmic reticulum. There, the RNA meets up with a ribosome, which is attached to the ER.
