Which cost best applies to the use of public warehousing by a firm?

The cost that best applies to the use of public warehousing by a firm is the variable cost associated with storage and handling. Public warehousing allows firms to pay for space and services based on their inventory needs, which can help manage costs more flexibly compared to fixed costs associated with owning and operating private warehouses. This arrangement can also include additional costs such as labor, utilities, and inventory management services, but the primary advantage lies in the scalability and reduced financial risk.
