Explanation:

An auction sale is a type of sale in which the goods or properties are sold to the highest bidder. When a person bids at an auction sale, he/she makes an offer to buy the goods or properties being sold. However, the nature of this offer is different from other types of offers.

The correct answer to this question is option 'B', which states that a bid at an auction sale is an express offer to buy. This means that when a person bids at an auction sale, he/she is explicitly stating that he/she is willing to buy the goods or properties being sold.

Why is a bid at an auction sale an express offer to buy?

To understand why a bid at an auction sale is an express offer to buy, we need to understand the different types of offers.

1. Implied offer to buy:

An implied offer to buy is an offer that is not explicitly stated but is implied from the actions or conduct of the parties. For example, if a person enters a shop and picks up a product, it can be inferred that he/she is making an offer to buy the product.

2. Express offer to buy:

An express offer to buy is an offer that is explicitly stated by the offeror. For example, if a person says "I offer to buy this product for $50", it is an express offer to buy.

3. Invitation to offer to buy:

An invitation to offer to buy is not an offer to buy, but an invitation to others to make an offer. For example, if a shopkeeper puts up a sign saying "Sale: 50% off on all products", it is an invitation to offer to buy, not an offer to sell.

Now, let us apply these concepts to an auction sale.

In an auction sale, the auctioneer is the offeror, and the bidders are the offerees. The auctioneer invites the bidders to make an offer by calling out the starting bid. When a bidder raises his/her hand and says "I bid $X", he/she is making an express offer to buy the goods or properties being sold. This is because the bidder is explicitly stating that he/she is willing to buy the goods or properties for the amount bid.

Therefore, a bid at an auction sale is an express offer to buy.

Conclusion:

A bid at an auction sale is an express offer to buy because the bidder is explicitly stating that he/she is willing to buy the goods or properties being sold for the amount bid. This is different from an implied offer to buy or an invitation to offer to buy.
