You are creating the CUST_PREMIUM data block in the AUTO_INSURANCE form. A new state law requires that premiums be lowered for drivers with a good driving history. Because this could potentially affect a large number of records, you want to base the data block on a stored procedure returning a table of records. Which statement supports this approach?（）
A:A table of records is efficient in terms of network traffic. 
B:A table of records improves developer productivity because the database administrator does not have to create a server side view. 
C:A table of records is efficient because the number of records fetched depends on the Array Fetch property value.
D:Your coding effort is simplified since DML operations are handles by setting form module properties.
