Question

Quizplus · Accepted Answer

The change in sourcing products from various suppliers indicates a change in the cardinality associated with the supplier side relationship. Previously, the relationship was likely one-to-one between the organization and the supplier. Now, with multiple suppliers, the relationship has changed to one-to-many or many-to-many. The other options (A, C, D) do not reflect this change in cardinality.
