The Answer Is:
D
This question includes an explanation.
Explanation:
The database object that should be used to create a virtual relation in a database to query the data is a view. A view is a searchable object that is defined by a query. It does not store any data but retrieves data from one or more tables at run time, creating a virtual table and returning the data in the defined format. It is created using joins, filters, aggregations, or other SQL operations. A view can be used to simplify complex queries, provide security, or enhance performance. Therefore, the correct answer is D.
