Tenancy at will is not a form of concurrent ownership, so B is correct. A tenancy at will is a landlord-tenant arrangement—a form of leasehold possession that generally continues without a fixed termination date until ended in accordance with applicable law. It gives the tenant possessory rights rather than co-ownership of the fee estate.
A married couple can own property as tenants by the entirety, a specialized form of concurrent ownership available to married spouses and carrying survivorship characteristics and other legal consequences. Depending on the conveyance, spouses may also hold property as joint tenants, which generally includes a right of survivorship, or as tenants in common, where each co-owner has an undivided interest but there is no automatic survivorship between them.
The Massachusetts Board contract-law curriculum expressly identifies month-to-month or periodic tenancy as a tenancy-at-will concept, confirming its leasehold character. Massachusetts property materials separately distinguish tenancy in common and joint tenancy as forms of ownership.
The exam technique is therefore to distinguish the word “tenancy” used in ownership estates from the same word used in landlord-tenant possession.
