You work for a bank that uses a SQL Server 2005 database to store line items from customer banking transactions. The bank processes 50，000 transactions every day. The application requires a clustered index on the TransactionID column. You need to create a table that supports an efficient reporting solution that queries the transactions by date. What are the two ways to achieve this goal？（）

A. Place a nonclustered index on the date column.
B. Add a unique clustered index on the date column.
C. Map each partition to a filegroup， with each filegroup accessing a different physical drive.
D. Create a partitioning scheme that partitions the data by date.
