You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. You create a DataSet object in the
application. You add two DataTable objects named App_Products and App_Categories to the
DataSet. You add the following code segment to populate the DataSet object. (Line numbers are
included for reference only.)
01 public void Fill(SqlConnection cnx, DataSet ds) {
03 var cmd = cnx.CreateCommand();
04 cmd.CommandText = “SELECT * FROM dbo.Products; ” + “SELECT * FROM dbo.Categories”;
05 var adapter = new SqlDataAdapter(cmd);
06
07 }
You need to ensure that App_Products and App_Categories are populated from the dbo.Products
and dbo. Categories database tables. Which code segment should you insert at line 06?

A.
adapter.Fill(ds, “Products”); adapter.Fill(ds, “Categories”);

B.
adapter.Fill(ds.Tables[“App_Products”]);
adapter.Fill(ds.Tables[“App_Categories”]);

C.
adapter.TableMappings.Add(“Table”, “App_Products”);
adapter.TableMappings.Add(“Table1”, “App_Categories”);
adapter.Fill(ds);

D.
adapter.TableMappings.Add(“Products”, “App_Products”);
adapter.TableMappings.Add(“Categories”, “App_Categories”);
adapter.Fill(ds);
