Answer:
A) Sale of goods
Step-by-step explanation:
When an individual or a business purchases a good (merchandise, product, object), the owner of the good is selling that good to the buyer.
When a good is leased, it means that it is being rented. This means that the leased good can be used by the lessor during a specific amount of time and them it must be returned.
