A Forward Auction

A forward auction:

A) occurs when a seller determines demand and then creates a product based on that price.
B) occurs when a buyer lists what he or she wants to buy and sellers may submit bids.
C) occurs when different offerings are sold together at a price that's typically lower than the total price a customer would pay by buying each offering separately.
D) occurs when a buyer lists what he or she wants to buy and also states how much he/she is willing to pay.
E) occurs when buyers pay the same price regardless of where they buy the product or from whom.
