What would be used to keep track of data movement between systems?

Embedded metadata is the correct choice for tracking data movement between systems. This type of metadata can be integrated directly within the data itself, allowing for a transparent trace of how the data is used or modified as it moves through different systems. It can include information such as data format, the origin of the data, and any transformations that the data undergoes. This provides a detailed and immediate view of the data's lineage and helps ensure that there are proper data governance practices in place.

Administrative metadata primarily focuses on the management aspects of data, including information on when and how data was created or accessed, but does not typically track movement between systems. Business metadata provides context about the data in relation to business processes and terminology, but it lacks the specificity needed to track data across systems. Context metadata offers insight into the circumstances surrounding data entry and its relevance but doesn’t specifically cover data movement like embedded metadata does.
