Hint: Cell organelles are a complex entity present within a specific cell type that always performs a particular role. Organelles either are concealed separately in their own lipid bilayers or are spatially distinct functional units without the need for an enveloping bi-layer membrane.

Complete answer: The nuclear membrane, the double membrane encapsulating the nucleus of eukaryotes, governs the information flow between the nucleolus and the cytoplasm, and provides the basis for the assembly of chromatin and cytoskeleton. Nuclear membrane development around daughter chromosomes is a membrane renovating event that happens during cell division. The nuclear membrane develops from the endoplasmic reticulum (ER) tubular network. The overall process will be conducted by the DNA-binding proteins found in the ER. Chromatin also plays an important role in the reconfiguration of the ER during the formation of the nuclear envelope. The outer nuclear envelope is consistent with the rough endoplasmic reticulum membrane (RER) and has been likewise jeweled with ribosomes.
So, the correct answer is (C).

Note: The nuclear membrane consists of two cellular membranes, the inner membrane and the outer membrane, structured parallel to one another and divided by 10 to 50 nm. The membrane approaching the cytoplasm is pointed to as the outer nuclear membrane and the membrane addressing the nucleoplasm is pointed to as the inner nuclear envelope. The inner layer is integrally linked to the ER, and its surface, like those of the ER, is covered with ribosomes.
