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.
