Explanation:

The question is related to the concept of sale of goods and different types of contracts related to it. Let us discuss each option one by one:

A) Sale: Sale is a contract in which the seller transfers the ownership of goods to the buyer for a price. In a sale, the property in goods passes from the seller to the buyer immediately at the time when the contract is made. The buyer becomes the owner of the goods as soon as the contract is concluded.

B) Agreement to Sell: An agreement to sell is a contract in which the seller agrees to transfer the ownership of goods to the buyer at a future date or on the happening of a certain event. In this type of contract, the property in goods does not pass to the buyer immediately. It will pass only when the conditions mentioned in the contract are fulfilled. An agreement to sell is also known as a conditional sale.

C) Hire-Purchase Contract: A hire-purchase contract is a type of agreement in which the seller agrees to transfer the ownership of goods to the buyer only when the buyer pays the total price in installments over a period of time. In this type of contract, the property in goods remains with the seller until the buyer makes the final payment. Hire-purchase contracts are commonly used for the sale of expensive items like cars, furniture, etc.

D) Sale on Approval: Sale on approval is a type of contract in which the buyer is given the opportunity to inspect the goods before making the final decision to buy them. The buyer can use the goods for a certain period of time and then decide whether to buy them or not. In this type of contract, the property in goods does not pass to the buyer until he/she approves the sale.
