You are implementing an EDM. You need to add a definition to the data model that creates a logical relationship between a Product entity and a ProductCategory entity.
Which type of definition should you add?

Association specifies a logical relationship between entities in the Entity Data Model. An association is declared and defined in the conceptual schema using CSDL. It does not represent a set.

An AssociationSet represents a particular type of data, such as a customer entity or an order entity in the EDM.
