What is often the largest component of logistics costs?

A) Inventory costs
B) Transportation costs
C) Shipper-related costs
D) Administrative costs

Transportation costs are often the largest component of logistics costs, as they can account for a significant portion of the total cost of moving goods from one location to another. Inventory costs can also be significant, but they are often more variable and dependent on factors such as order size and frequency. Shipper-related costs and administrative costs can also add to logistics expenses, but they are typically less significant than transportation and inventory costs.
