The image is a depiction of a Golgi apparatus labeled at the cis face and monitored for 12 hours. The golgi apparatus showing rows of vesicles, cis at left and trans at right in 3 images at 0 hours, 6 hours, and 12 hours. At 0 hours, dark vesicles are on the cis side moving to the trans side. At 6 hours, the dark vesicles are moving to the trans side and are scattered throughout. At 12 hours, some vesicles are moving to trans, some to cis.

Based on the data, taken at three different time points, which of the following statements best describes what is observed in the image?

A. The Golgi apparatus is dynamic. The vesicles moved exclusively from the cis face to the trans face.
B. The cisternae of the Golgi apparatus did not change in structure between the cis face and the trans face.
C. The secretory proteins are packaged and tagged for transport as they moved from the trans face to the cis face.
D. The Golgi apparatus can recycle vesicles. Some vesicles moved from the trans face to the cis face for recycling.
