Concept:Auction sale is a public system of selling goods to the highest bidder.
Explanation:In an auction, several buyers compete by placing bids on the goods.
Each bid is made openly, and buyers try to offer more than the previous bid.
The bidding continues until no buyer is willing to raise the price further.
The person who places the highest bid wins the sale and gets the goods.
This method is often used for valuable or unique items, property, and surplus stock.
A credit sale allows payment after the goods are received.
Hire purchase involves paying in installments while using the goods.
A clearance sale means selling goods at reduced prices to remove old stock.
Only an auction sale depends on the highest bidder.
Thus, the correct choice is the auction method of selling.
