Which of the following describes a reserve auction?

A reserve auction is characterized by the seller having the discretion to reject bids that do not meet a certain confidential minimum price, often termed the "reserve price." This allows the seller to maintain control over the sale, ensuring that they do not sell the property for less than they are willing to accept. In contrast, if the highest bid does not meet the reserve price, the seller can choose not to complete the sale, thus protecting their financial interests.

This format contrasts with a few other auction types. For example, in an absolute auction, the seller must accept the highest bid regardless of the amount, which is not the case in a reserve auction. Moreover, while bids in a reserve auction can be confidential, that confidentiality means that not all bids may be public knowledge.

The option stating it is a forced sale without reserve describes a different auction type where the property must be sold to the highest bidder without a reserve price, weakening the seller's position. Thus, the correct understanding of a reserve auction underscores the seller's ability to reject insufficient bids, thereby setting it apart from other auction formats.
