Final answer:
The MRIR (option A)(Material Receipt and Inspection Report) is the transaction used to verify items in a consolidated shipment have been received and processed. It is essential for supply chain management and recording inventory updates.
Step-by-step explanation:
For a consolidated shipment, the transaction processed to verify that the items contained in the consolidation have been received and processed is commonly referred to as a Material Receipt and Inspection Report (MRIR). When a consolidated shipment arrives, the MRIR serves as the documentation that confirms the goods have been received in the expected condition and quantity. This transaction is critical in supply chain management as it provides an official record of the inventory being added to the company's stock and is necessary for updating the company's inventory system as well as for future planning and audit purposes.
