B. Store the results of the query in a static Data Table object that is used by all the forms.
C. Design a static class for the data that implements the IObservable interface. Subscribe to the static class from each of the forms that use the datA.
D. Design a static class for the data that implements the INotifyPropertyChanged interface. Raise the PropertyChanged event to notify the forms when data is changed.
