The correct answer is: B. Hire Purchase
Hire purchase is a type of credit agreement where the buyer agrees to pay for goods in installments over a period of time. The buyer takes possession of the goods immediately, but the seller retains ownership until the final payment is made. This is different from a normal sale of goods, where the buyer takes possession and ownership of the goods at the time of purchase.
A rent-a-car is a type of contract where the renter agrees to pay a fee for the use of a car for a specified period of time. The renter does not own the car and must return it to the rental company at the end of the rental period.
A normal sale of goods is a transaction where the buyer agrees to pay the seller a price for goods, and the seller agrees to transfer ownership of the goods to the buyer. The buyer takes possession of the goods at the time of purchase.
Therefore, the only option that meets the criteria of the question is hire purchase.
