You develop an inventory management application called XYZManagement that will call a Microsoft SQL Server stored procedure named sp_GetDailyXYZSales. The stored procedure will run a query that returns your daily sales total as an output parameter. This total will be displayed to users in a message box. Your application uses a SqlCommand object to run sp_GetDailyXYZSales. You write the following code to call sp_GetDailyXYZSales: SqlConnection cnn = new SqlConnection(myConnString); SqlCommand cmd = new SqlCommand(“sp_GetDaily XYZ Sales”, cnn); cmd.CommandType = CommandType.StoredProcedure; SqlParameter prm = cmd.Parameters.Add(“@ItemTotal”,SqlDbType.Int); prm.Direction = ParameterDirection.Output; cnn.Open(); cmd.ExecuteNonQuery(); Now you must write additional code to access the output parameter. Which code segment should you use?

A) MessageBox.Show(?Total is: ? + cmd.Parameters[?@Output?].Value.ToString());

B) MessageBox.Show(?Total is: ? + cmd.Parameters[?@Output?].ToString());

C) MessageBox.Show(?Total is: ? + cmd.Parameters[?@ItemTotal?

D) MessageBox.Show(?Total is: ? + cmd.Parameters[?@ItemTotal?
