You need to create a canvas app. The app should add a record to the SharePoint list and send a mobile notification about the list`s update when a user pushes a screen button. 
What Power Platform product will you use for this functionality?

Answer options:

A.Power BI
B.Power Automate
C.Power Virtual Agents
D.AI Builder
E.SharePoint

Correct Answer: B 
Power Platform product integration helps users to extend the functionality of the Power Apps with Power Automate. 
You need to create an instant (or button) blank flow in Power Automate first and use Power Apps as a trigger. Then you add a SharePoint action and provide the list`s address and name (Number 1 and 2). Flow designer will populate the next field label with the first list`s column name (Number 3). The value for this column comes from the canvas app. When you click on the field, Dynamic content pops up with the link to PowerApps: "Ask in PowerApps" (Number 4). After you select this tag, the designer puts a new page in the field for the column. Then you can add a mobile notification in the next step. After you save the flow, you return to the canvas app. 
Now you can add the newly created flow to your button in the app. Select the button, and on the Action menu, select Flows and your freshly created Flow with a new item for the SharePoint list as a parameter. 

All other options are incorrect.
