The following image displays the execution plan the query optimizer generates for this query:

Users frequently run the same query with different values for the local variable @lastName. The table named
Person is persisted on disk.
You need to create an index on the Person.Person table that meets the following requirements:
1. All users must be able to benefit from the index.
2. FirstName must be added to the index as an included column.
What should you do?

A.
Create a clustered index on the table.

B.
Create a nonclustered index on the table.

C.
Create a nonclustered filtered index on the table.

D.
Create a clustered columnstore index on the table.

E.
Create a nonclustered columnstore index on the table.

F.
Create a hash index on the table.

Explanation:
By including nonkey columns, you can create nonclustered indexes that cover more queries. This is because
the nonkeycolumns have the following benefits:
They can be data types not allowed as index key columns.
They are not considered by the Database Engine when calculating the number of index key columns or index
key size.
