Final answer:
Marvin's timeshare is a Right-to-use timeshare where he has the right to use a resort unit for two weeks every year without owning the property itself. Hence, the correct answer is option C.
Step-by-step explanation:
This type of timeshare is called a Right-to-use timeshare.
With a right-to-use timeshare, a person purchases the right to use a property for a specific period of time each year, usually for a fixed number of years. However, the person does not own the property itself and is not responsible for its maintenance or other costs associated with ownership.
In Marvin's case, he has the right to use the resort unit for two weeks every year, but he does not own the property. This means that he can enjoy his vacation at the resort for those two weeks, but he does not have any ownership rights or responsibilities for the property.
