C is correct. In this case, the school district's interest was a fee simple determinable (meaning it could be terminated), and the testator's interest was a possibility of reverter. According to the facts, the only event that could terminate the school district's interest would be to cease using the land for «school purposes.» When that event occurred, the school's interest terminated and the land reverted back to the testator.

B is incorrect. Because the school district terminated their interest by selling Blackacre to the developer, the interest in Blackacre reverted back to the testator, whose heir was the friend. However, if the testator had not bequeathed his estate to the friend, then the interest would have reverted to the testator's son as the testator's only heir.

D is incorrect. The school district terminated its own interest in Blackacre.
