You administer a Microsoft SQL Server 2012 database that contains a table named AccountTransaction.
You discover that query performance on the table is poor due to fragmentation on the IDX_AccountTransaction_AccountCode non-clustered index.
You need to defragment the index. You also need to ensure that user queries are able to use the index during the defragmenting process.
Which Transact-SQL batch should you use?
A. ALTER INDEX IDX_AccountTransaction_AccountCode ON AccountTransaction.AccountCode REORGANIZE
B. ALTER INDEX ALL ON AccountTransaction REBUILD
C. ALTER INDEX IDX_AccountTransaction_AccountCode ON AccountTransaction.AccountCode REBUILD
D. CREATE INDEX IDXAccountTransactionAccountCode ON AccountTransaction.AccountCode WITH DROP EXISTING
