Final answer:
Manufacturing planning and control involve inputs such as customer orders and finished goods inventory, both of which are essential in making informed production decisions.
Step-by-step explanation:
The inputs to manufacturing planning and control include multiple aspects of a business that inform the process of planning and managing the production of goods. In particular, option A, customer orders, and option B, finished goods inventory, are both critical inputs.
Customer orders drive the demand forecasting and production scheduling aspects of manufacturing planning, as they reflect the actual demand for products. Finished goods inventory levels are necessary for inventory control and to inform production decisions based on current stock versus expected demand. Therefore, the accurate answer is C. Both A and B are inputs to manufacturing planning and control.
