1. The problem is to match each category of inventory with its supported function. 2. The categories given are work-in-process, spare parts, and indirect materials. 3. Work-in-process inventory supports production because it consists of items currently being manufactured. 4. Spare parts inventory supports maintenance, repair, and other activities as these parts are used to fix or maintain equipment. 5. Indirect materials inventory supports customer service as these materials are used in activities that indirectly support the production or service process. 6. Therefore, the correct matches are: - Work-in-process: production - Spare parts: maintenance, repair, and other activities - Indirect materials: customer service This matching ensures that each inventory category is aligned with its primary function in the business process.
