You have a table containing employee information that your users query frequently. They spe- cifically use this query most often:

SELECT FirstName, LastName, Address, Phone

FROM Employees WHERE SSN = ssn

You have a clustered index on this table on the SSN column, but your users are complaining that the query is still too slow. What can you do to speed it up?

A. Modify the index to include the FirstName, LastName, Address, and Phone columns as nonkey columns.

B. Create a new nonclustered index on the FirstName, LastName, Address, and Phone columns.

C. Create a new clustered index on the FirstName, LastName, Address, and Phone columns.

D. You cant do anything to speed up this query.
