In inventory control, the maximum inventory level is the upper limit of stock you carry. It’s reached after you receive a replenishment and just before you start consuming again, so it reflects the peak stock position. This peak equals the safety stock (buffer inventory) plus the size of the replenishment order (the maximum reorder quantity). The safety stock protects against variability in demand or lead time, while the order quantity is what you add when you replenish. So the highest stock you hold in a cycle is buffer inventory plus the maximum reorder quantity. The other options describe lower levels or different concepts (like the trigger point to reorder or the rate of usage), not the peak stock. For example, if you hold 100 units as safety stock and order 400 units each time, the maximum stock level you’d carry is 500 units.
