B. DataSet ds = new DataSet(); ds.ExtendedProperties["RowCount"] = 10; ds.ExtendedProperties["RowIndex"] = 0; adapter.Fill(ds);
C. DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Product"); adapter.Fill(0, 10, dt);
D. DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Product"); dt.ExtendedProperties["RowCount"] = 10; dt.ExtendedProperties["RowIndex"] = 0; adapter.Fill(dt);

Question 2
