You create a Web Form that displays a GridView. The GridViews data source is a DataSet named dsOrders. The DataSet contains two DataTables named Orders and OrderDetails. You create a relation between the two DataTables using the following code segment.

What should you do? ()A、Ensure that the child column and the parent column have the same names.B、Ensure that the child table and the parent table have the same names.C、Ensure that the child column and the parent column have the same data types.D、Ensure that each row in the child table has a corresponding row in the parent table.E、Ensure that the tables have an explicit relationship defined by a foreign key constraint in the database.
