Which of the following items can be purchased through commodity resale?

Purchasing gasoline through commodity resale is correct because this process allows public entities to buy goods at a lower cost by pooling resources and negotiating bulk prices. Commodity resale is often utilized for items that are consistent in demand and can benefit from economies of scale. Gasoline fits this category since it is a standard commodity often needed by municipalities for their vehicles and equipment.

On the other hand, furniture, office supplies, and computers do not generally fall under the typical category of commodities that are resold. These items can vary significantly in specifications and quality, making them less suited to bulk purchasing agreements that benefit from commodity resale practices.
