This REA diagram consists of 6 entity types (Supplier, Inventory Item, Purchase Order, Purchase Order Line Item, Invoice, Invoice Line Item) and 5 resource types (Cash, Accounts Payable, Inventory, Accounts Receivable, and Revenue). 
To translate the REA diagram to a relational database, each entity and resource type would typically become a table, resulting in a total of 11 tables (6 entity tables and 5 resource tables). 
Therefore, the answer is B as 11 tables are needed.
