Which code segment should you insert at line 02?

You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.

The application contains a SqlDataAdapter object named daOrder. The SelectCommand property of the daOrder object is set.
You write the following code segment. (Line numbers are included for reference only.)

01 private void ModifyDataAdapter() {
02
03 }

You need to ensure that the daOrder object can also handle updates.

daOrder.DeleteCommand = cb.GetDeleteCommand();
daOrder.InsertCommand = cb.GetInsertCommand();
daOrder.UpdateCommand = cb.GetUpdateCommand();

cb.RefreshSchema();
cb.GetDeleteCommand();
