From where do models for SAC insight apps dashboards originate?

The correct choice is that the models for SAP Analytics Cloud (SAC) insight apps dashboards originate from Datasphere. Datasphere serves as a unified data foundation and can integrate data from various sources, enabling the creation of analytic models that power the dashboards in SAC.

Datasphere promotes seamless connectivity to both SAP and non-SAP data sources, offering a comprehensive data management solution that enhances analytical capabilities. By utilizing Datasphere, users can derive insights from a vast array of data, ensuring that SAC dashboards are built on a solid and versatile foundation of information.

While other options may also represent data storage or management systems, they do not specifically align with the primary functionality of providing models for SAC insight apps dashboards as effectively as Datasphere does.
