You create a custom chart and want to add it to a model-driven app dashboard. 
What type of dashboard would you create?

Answer options:

A.Custom
B.Admin
C.Standard
D.System
E.Interactive

Correct Answer: C 
Power Apps studio provides the three main data visualization components for model-driven apps: Chart
Dashboard
Embedded BI
The model-driven app can use two types of dashboards: Standard — displays a collection of one or more unrelated components, like charts and lists.
Interactive — provides the capability of the record visualization with filtering and acting upon.
If you need to add a chart to the model-driven dashboard, you will create a standard dashboard. 
All other options are incorrect.
