Answer:
The correct answer is D) length of time between the order and delivery of a product. : )
Step-by-step explanation:
When calculating basic stock, you must also factor in lead time—the length of time between reordering and receiving a product. For instance, if your lead time is four weeks and a particular product line sells 10 units a week, then you must reorder before the basic inventory level falls below 40 units. If you do not reorder until you actually need the stock, you’ll have to wait four weeks without the product.
