Which statement highlights the difference between data types and field groups?

The correct choice emphasizes that a field group can be added directly to a schema, whereas a data type cannot be added in the same manner. In Adobe Experience Platform, field groups are collections of fields that are organized to represent a specific aspect of data, and they can be integrated easily into different schemas. This flexibility allows users to structure their data in a way that is more aligned with their needs and makes it simpler to manage and reuse across various schemas.

On the other hand, data types serve as definitions for the format and structure of individual fields but are not directly added to schemas. Instead, they are utilized when creating fields that define the kind of data expected. This distinction highlights the specific role of field groups in schema configuration, allowing for modular and reusable design in data modeling.
