✑ Dynamic (Option C): A dynamic dashboard allows for interactivity and can be updated as data changes, complementing real-time delivery.
✑ Static (Option D): Static dashboards don??t update automatically, making this incorrect.
✑ Ad hoc (Option E): Ad hoc delivery is for one-time reports, not ongoing updates.
✑ Time series (Option F): Time series refers to a data type or visualization, not a delivery method.
