Power BI Quiz - need clarification on a question

[Anonymous]

I have this question before me. Can anyone let me know the answer ?

You plan to use Power BI Desktop to create a report. The report will consume data from an on-premises
tabular named SalesDB in Microsoft SQL Server Analysis Services (SSAS). The report will be published
to the Power BI service. You need to ensure that the report published to the Power BI service will
access the current data in SalesDB. What should you do?

A. Deploy an on-premises data gateway and configure the connection to SalesDB to use the Import Data Connectivity mode.
B. Deploy an on-premises data gateway and configure the connection to SalesDB to use the Connect live option.
C. Deploy an on-premises data gateway (personal mode) and configure to SalesDB to use the DirectQuery Data Connectivity mode.
D. Deploy an on-premises data gateway and configure the connection to SalesDB to use the DirectQuery Data Connectivity mode.

Is the correct answer B or D ?

Its D, we can do a direct query on DB to get the latest data and that can be possible with on-premises data gateway
