Your application uses the following code to submit changes to a database using a strongly typed DataContext named db:
catch (ChangeConflictException e)
foreach (ObjectChangeConflict occ in db.ChangeConflicts)
// Overwrite values
You must add code to resolve conflicts such that:
* Original property values of changed properties must not be overwritten with values received from the database.
* Client changes to properties must be preserved.
What should you do?

Select from following answers:
Call ObjectChangeConflict.Resolve with KeepChanges.
Call ObjectChangeConflict.Resolve with OverwriteCurrentValues.
Calling ObjectChangeConflict.Resolve with KeepChanges forces the Resolve method to keep the current value that has been changed, but it updates (merges) other values with the database values. Current, modified values are preserved.
Calling ObjectChangeConflict.Resolve with KeepCurrentValues forces the Resolve method to swap the original value with the values retrieved from the database. Current, modified values are preserved.
