Answer: Option C) selective barrier that separates nuclear and cytoplasmic constituents, localizes chromosomes within the cell, and sequesters many of the mRNA processing activities from the cytosol.

Explanation:

The nuclear membrane is a double membrane surrounding the nucleus of eukaryotes. It consists of outer and inner membranes perforated by nuclear pores. Thus, it serves as a selective barrier between the nucleus and cytoplasm, also restricting post translational modification activities to the nucleus. As well, the nuclear envelope is absent in prokaryotes.
