___________ allows the movements of materials between cytoplasm and nucleoplasm.NucleusGolgi apparatusNuclear membraneNucleolus

The correct answer is Nuclear membrane.

Explanation:

The nuclear membrane, also known as the nuclear envelope, is a double-layered membrane that surrounds the nucleus of a eukaryotic cell. It serves several important functions: it protects the genetic material within the nucleus and regulates the transportation of materials between the cytoplasm and nucleoplasm. The nuclear membrane is punctuated by nuclear pores, which are complexes that allow the selective exchange of various substances, such as ions, RNA, and proteins, thus facilitating necessary communication between the nucleus and the rest of the cell. Other options like the nucleus, Golgi apparatus, and nucleolus serve different roles and do not facilitate direct transport between the cytoplasm and nucleoplasm.
