Which Transact-SQL command should you use?

You administer a Windows 2008 server hosting an instance of Microsoft SQL Server 2012 Standard Edition. The server hosts a database named Orders.

Users report that a query that filters on OrderDate is taking an exceptionally long time. You discover that an index named IX_OrderDate on the CustomerOrder table is heavily fragmented.

You need to improve the performance of the IX_OrderDate index. The index should remain online during the operation.

Which Transact-SQL command should you use?
A . ALTER INDEX IX_OrderDateON CustomerOrderDISABLE
B . ALTER INDEX IX_OrderDateON CustomerOrderENABLE
C . ALTER INDEX IX_OrderDateON CustomerOrderREORGANIZE
D . ALTER INDEX IX OrderDateON CustomerOrderREBUILD
