What conveys to a tenant the right to possess a fee owner's real estate?

The correct choice is a leasehold estate because it specifically grants a tenant the legal right to possess and use the property owned by a fee owner for a specified period, under certain conditions outlined in a lease agreement. A leasehold estate establishes a contractual relationship between the landlord (fee owner) and the tenant, defining the terms of occupancy, rent payments, and the rights and obligations of both parties.

In contrast, a temporary estate does not provide a tenant with the same legal rights as a leasehold estate; it may refer to short-term arrangements without the formalities and protections of a lease. A sublease, while it can involve tenants, does not convey possession directly from the fee owner but rather from an existing tenant who has sublet their interest in the property. An easement, on the other hand, grants a right to use someone's land for a specific purpose (such as access), but it does not convey possession or the right to inhabit the property as a tenant would under a leasehold estate.
