Solution
The correct option is C Golgi apparatus
Transport vesicles(proteins) bud off from the ER, travel to thecisface of the Golgi, fuse with it, and empty their contents into the lumen. As proteins and lipids move forward through the Golgi, they may undergo a series of modifications. Some proteins may have a new carbohydrate group attached to them, while others have their existing carbohydrate groups modified. Many of these are delivered to the plasma membrane, where transmembrane proteins are integrated into the membrane and freely floating proteins are released to the space outside the cell. Other vesicles may be delivered to destinations inside the cell, such as the lysosome or vacuole.
