Verified by Experts

The correct Answer is:
B
ER functions as cytokeleton or intracellular and ultrastructural skeletal framework by providing mechanical support to cooloidal cytoplasmic matrix. The ER may act as a circulatory system for intracellular circulation of various substances. Membrane flow may also be an important mechanism for carrying particles, molecules and ions into and out of the cells.
