Answer: Option C. During exocytoiss, substances moved from inside the cell are moved outside.

Explanation:

Exocytosis is the process of moving substances from inside (interior) the cell to the outside (exterior) of the cell. This process requires energy and is therefore a type of active transport. Unlike endocytosis, exocytosis does not rely on protein interactions with the plasma membranes. In exocytosis, membrane-bound vesicles containing cellular molecules are transported to the cell membrane. The vesicles join with the cell membrane and depose their contents to the exterior of the cell
