Which of the following best describes the role of a buyer in an auction?

The role of a buyer in an auction is primarily to bid for items they wish to purchase during the auction. This involves actively participating in the bidding process, where buyers express their willingness to pay a particular price for an item. The dynamics of an auction revolve around the buyer's actions, as their bids drive the competition for items and ultimately establish their final selling price.

While buyers may perform tasks such as evaluating items before the auction or setting a reserve price, these actions are not central to their primary role. The reserve price, for example, is typically set by the seller or auction house as a minimum acceptable price, and the organization of the auction is the responsibility of the auctioneer or event planners. Therefore, the key function of a buyer is engaging in the auction by making bids, which highlights their role in the auction process.
