You have an Azure SQL database named DB1. You run a query while connected to DB1. You review the actual execution plan for the query, and you add an index to a table referenced by the query. You need to compare the previous actual execution plan for the query to the Live Query Statistics. What should you do first in Microsoft SQL Server Management Studio (SSMS)?
A. For DB1, set QUERY_CAPTURE_MODE of Query Store to All.
B. Run the SET SHOWPLAN_ALL Transact-SQL statement.
C. Save the actual execution plan.
D. Enable Query Store for DB1.
