The correct answer is:
a The Golgi apparatus modifies, sorts, and packages proteins for transport, with the vesicles transporting the packages to various locations.
In an animal cell, the Golgi apparatus plays a critical role in processing and packaging proteins synthesized in the endoplasmic reticulum. Once proteins are modified in the Golgi, vesicles bud off and transport these proteins to their required destinations, such as the cell membrane, lysosomes, or for secretion outside the cell.
