When she died, Clara left a valid holographic will that contained the following provision: I want my only child, Truman, to have my house when I die and to live there as long as he wants. After that, I want it to go to my grandchildren. At the time of Clara's death, Truman was married to Dina, and they had a married son, Sam. Both Truman and Dina moved into the house, but about six months later, they separated and Dina moved out. The following year, Truman and Sam were involved in an airplane crash in which Truman was immediately killed. Several weeks later, Sam died, leaving his young widow, Tanya. Dina brings a suit against Tanya claiming an interest in the house as Truman's widow. There is no statute in this jurisdiction that governs the issue of the right of an estranged spouse to inherit property from a decedent spouse, but if Truman is found to own property at the time of his death, it is possible that Dina could inherit one-half as his surviving spouse. In this suit, Dina should most likely:
A. Prevail, because Clara's will gave Truman a fee simple interest in the property.
B. Prevail, because the devise to Clara's grandchildren in her will is invalid as it violates the Rule Against Perpetuities.
C. Not prevail, because Sam had a vested remainder interest subject to open, which became indefeasibly vested. 
Choose A, B, C or D as your solution.
