Which of the following cell organelles surrounds the nuclear membrane?

Rough

endoplasmic

reculum

I think the correct answer from the choices listed above is the second option. It is the endoplasm the cell organelle that surrounds the nuclear membrane. It is the inner, dense part of the cytoplasm of a cell. It is full of proteins that control the metabolism of the cell.

Endoplasm, because it is the inner relatively fluid part of the cytoplasm which is a part of a cell.
