You are creating a Windows Forms application for inventory management by using the .NET Framework 3.5.
The application provides a form that allows users to maintain stock balances. The form has the following features:
* A dataset named dsStockBalance to store the stock information.
* A business component named scInventory
* The scInventory component provides a method named Save.
* You need to ensure that only the modified stock balances of dsStockBalance are passed to the scInventory.Save method.
Which code segment should you use?

A.
if(dsStockBalance.HasChanges()) dsStockBalance.AcceptChanges();
dsUpdates = dsStockBalance.GetChanges();
scInventory.Save(dsStockBalance);

B.
if(dsStockBalance.HasChanges()) dsUpdates = dsStockBalance.GetChanges();
dsStockBalance.AcceptChanges();
scInventory.Save(dsStockBalance);

C.
if(dsStockBalance.HasChanges()){ dsStockBalance.AcceptChanges();
dsUpdates = dsStockBalance.GetChanges(); scInventory.Save(dsUpdates);}

D.
if(dsStockBalance.HasChanges()){
dsUpdates = dsStockBalance.GetChanges();
dsStockBalance.AcceptChanges();
scInventory.Save(dsUpdates);}
