You need to be able to retrieve data from DataSet object that has four DataTable objects. There are currently UniqueConstraint and ForeignKeyConstraint Object on the DataTable objects to enforce the data rules. You find that you can retrieve the data from the individual DataTable objects, but you are not able to retrieve the data from the combination of DataTable objects in a Parent/Child manner. What should you do to able to retrieve the data in a Parent/Child manner? a) Set the EnforceParentChild parameter of the DataSet to True. b) Set the EnforceRelation parameter of the Relations collection to True. c) Add DataRelation objects to the Relations Collection to make the DataSet present the data in Parent/Child manner. d) Add a primary key and a foreign key to each of the DataTable objects that should present the data in a Parent/Child manner.
