Which of the following items might a local contracting unit purchase for resale?

A local contracting unit may purchase fuel and snow removal chemicals for resale because these items are directly related to the services that the contracting unit provides. Specifically, fuel is often necessary for operating vehicles and equipment used in public works, while snow removal chemicals are crucial for maintaining public safety during winter weather conditions. By purchasing these items for resale, the contracting unit can ensure that they have the necessary supplies to efficiently carry out their operations, fulfilling public needs effectively.

The other items are typically not classified the same way. Office supplies, furniture, and clothing generally do not fall under the category of items that a contracting unit would purchase with the intent to resell. Office supplies and furniture are usually for internal use, while clothing is likely considered a consumable expense rather than a resale item. Thus, fuel and snow removal chemicals stand out as the appropriate category for resale in this context.
