单项选择题

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.
