After Oliver's death, how did Rhonda own the old schoolhouse they bought together as joint tenants?

In joint tenancy, when one party passes away, their ownership interest in the property automatically transfers to the surviving joint tenant through the right of survivorship. This means that if Oliver and Rhonda had been joint tenants, upon Oliver’s death, Rhonda would fully own the old schoolhouse as the sole remaining owner.

The correct answer implies that after Oliver's death, Rhonda owned the property in severalty, meaning she is the sole owner. This situation typically occurs when there is no surviving joint tenant, or the joint tenancy was not established, resulting in the property being transferred to Rhonda without passing through Oliver's estate or to his heirs. In contrast, the other options suggest different forms of ownership that do not apply in this scenario, such as sharing ownership with Oliver's heirs or establishing a trust, both of which would not align with a straightforward transfer of ownership resulting from the death of a joint tenant.
