Answer: B. ask
Step-by-step explanation:
The ask also known as the offer price is the price at which seller is willing to sell a security after which the buyer must have stated a bid price of how much he or she wants to pay for the security. The bid price is known to be always lower than the ask price , of which the difference between both prices is called a bid-ask spread.
For example, if an investor wants to buy a security, he or she will first determine how much the seller is willing to sell it for, which is the ask price--- least price the seller is willing to sell the security for. However on the other hand, the seller in order to sell his or her security will first determine the highest price at which a buyer would be willing to pay for the security.
