The client hands you a supplier file and transaction file, but isn't sure how to connect the tables together. Which is the most logical:

	a.	Primary Key of Supplier ID in the Supplier File connected to the Primary Key of Supplier ID in the Transaction File
	b.	Primary Key of Supplier ID in the Supplier File connected to the Foreign Key of Supplier ID in the Transaction File
	c.	Foreign Key of Supplier ID in the Supplier File connected to the Primary Key of Supplier ID in the Transaction File
	d.	Foreign Key of Supplier ID in the Supplier File connected to the Foreign Key of Supplier ID in the Transaction File
