The answer is: B
Explanation
The correct option is B: Invitation to Offer.
Exposure of goods by a shopkeeper is not an offer to sell, but an invitation to the customers to make an offer to buy. This is based on the principle that the shopkeeper has the right to accept or reject the offer made by the customer. This was established in the case of Pharmaceutical Society of Great Britain v Boots Cash Chemists (Southern) Ltd, where the court held that the display of goods in a self-service store was not an offer, but an invitation to treat.
Therefore, the shopkeeper is not bound to sell the goods at the displayed price, and can withdraw or change the price before the customer pays for them.
