They are the Vendor Negotiation stage of the business-to-business buying process

The correct option is D. Vendor Negotiation

Explanation:

Vendor negotiation is the process whereby a buyer and a seller discuss the terms of a trade, such as price, quantity, quality, and so on. This discussion will either lead to an agreement and the deal is sealed, or it will lead to a disagreement and both parties go their way.

In the case of USF Corporation above, since they are already discussing the price, quality, and delivery schedules, it means they have secured a supplier who will be capable of meeting the terms of the corporation.

In this stage, the corporation will carry out the negotiations in order to get the best value for its money.
