The correct answer is:
a The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the cell.
In an animal cell, the Golgi apparatus modifies, sorts, and packages proteins that have been synthesized in the endoplasmic reticulum (ER). Once the proteins are processed, they are encapsulated in vesicles, which then transport these proteins to their destination, either inside the cell or for secretion outside the cell.
