Just in time

Hi, Does just in time imply low reorder costs? If so, why? I came across 2 different MCQ's regarding JIT and both of them have contradicting answers The following statements refer to different types of inventory control systems and procedures. 1 A just?in time system implies relatively low reorder costs. 2 Periodic review means ordering inventory when it falls below the designated safety inventory level. 3 Use of the economic order quantity model means that holding and ordering costs should be the same. Which of the above statements is/are correct? A 1 only B 1 and 3 only C 2 and 3 only D 1, 2 and 3 The correct answer: B (This answer is given in Kaplan the question is Green Co for ref) With deliveries being made on a daily (or more frequent) basis, ordering costs need to be low compared to the benefits of holding inventory. Under the EOQ model, holding costs and ordering costs are balanced off, with the EOQ being at the point where these are equal to each other. Periodic review means ordering inventory at a fixed and regular time interval. Inventory levels are reviewed at a fixed time. The inventory in hand is then made up to a predetermined level. Statements (1) and (3) are correct. The other question says: Which TWO of the following are aims of a Just in Time system of inventory control? A Reduction in capital tied up in inventory B Creation of an inflexible production process C Elimination of all activities performed that do not add value D Lowering of inventory ordering costs The correct answer: A and C The system aims to create a flexible production process that is responsive to the customer’s requirements, not an inflexible process (B). With a Just in Time system, although inventory holding costs are close to zero, inventory ordering costs are high, not low as more frequent small deliveries of supplies will be needed (D). I don't understand how JIT implies to relatively lower reordering costs if it said holding cost I would have agreed
