Incorrect Answers

A: The Merge method is used to merge two DataSet objects that have largely similar schemas. In this scenario we want combine the information from the DataTable objects, not merge them B: Creating a primary key for each Data Table object would not relate the DataTable objects. C: We should use a Datarelation, not a foreign key constraint, to relate the DataTable objects.

Note: A foreign key constraint represents an action restriction enforced on a set of columns in a primary key/foreign key relationship when a value or row is either deleted or updated.
