Which type of property often has a shorter occupancy period compared to standard leases?

D is the correct choice because motel rooms typically have a much shorter occupancy period compared to standard leases. Motel stays are often for a few nights or even a single night, catering primarily to travelers or those in need of temporary accommodation. This is in contrast to residential properties which may involve longer-term leases, usually lasting several months to a year.

Commercial properties can also involve longer terms, as businesses usually require stability for their operations. Vacation rentals may have shorter terms as well, but they are often reserved for entire weeks or months, especially during peak seasons. Motel rooms, on the other hand, are designed for quick, short stays, making them the clearest example of properties with a notably shorter occupancy period.
