How do proteins move out of the nucleus?

Through diffusion
Through active transport
Through endocytosis
Through exocytosis

The correct answer is: Through exocytosis

Proteins move out of the nucleus through a process called exocytosis, which is the release of substances from inside the cell to the outside. Diffusion (choice A) and active transport (choice B) are methods of moving molecules or ions across the cell membrane, not out of the nucleus. Endocytosis (choice C) is the opposite of exocytosis, as it is the process of transporting substances from outside the cell into the cell. Therefore, choices A, B, and C are incorrect because they do not describe how proteins specifically move out of the nucleus.
