Answer: Breach of the warranty of quiet enjoyment.(B)
Step-by-step explanation:
The warranty of quiet enjoyment is when a future covenant is breached due to interference with possession. Since the action of charity conflicts with the developer’s possession of the lot, it means the warranty has been breached. The developer may then assert the breach against the nephew.
The nephew breached the warranty of the right to convey, and this is a present covenant. The lessee has the right of quiet enjoyment and the possession of property, and the possession should not be disturbed by anybody.
