Answer:
D) The nuclear envelope is continuous with the endoplasmic reticulum.
Explanation:
In eukariotes, the nuclear envelope is a membrane that encloses the nucleus and protects by keeping its contents inside and other substances outside.
This membrane is continuous with the endoplasmic reticulum, connecting the space between the membranes (perinuclear space) and the lumen of the endoplasmic reticulum. This connection permits the movement of different types of molecules across both membranes.
