Answer :
Answer: passes to his wife, assuming she did not intentionally bring about Behan's death
Explanation:
We should note that Behan's interest to the described real property, upon the death of Behan will pass to his wife, assuming she did not intentionally bring about Behan's death.
Since they both own tne property as tenants and is a conditional estate, it simply means that the survivorship rights should be passed to another owner which is the wife in this case as long as the wife isn't responsible for his death.
