Final answer:
Without specific data on usage, cost, or sales of item code #1289, it is not possible to categorize it in the ABC classification system used in inventory management. Hence, the answer is (d) Insufficient information.
Step-by-step explanation:
According to an ABC classification system, which is used in inventory management to categorize items based on their importance and value to the company, it's not possible to categorize item code #1289 without additional information. In the ABC system, Class A items typically represent 10-20% of the inventory but account for 70-80% of the consumption value, Class B items are a moderate portion of inventory with a correspondingly moderate consumption value, and Class C items typically make up the majority of inventory but only account for a small portion of the consumption value.
To classify an item within this system, one would need data on the annual consumption value, unit cost, or sales data related to item code #1289. Without specifics on L. Houts Plastics' usage, costs, or sales information for this item, the correct classification cannot be determined. Therefore, the answer is (d) Insufficient information.
