Final answer:
A special warranty deed provides guarantees of title for the period that the grantor owned the property, not for all time or from the origin of the property ownership. Option b.
Step-by-step explanation:
When Luke gives Diana a special warranty deed, he is providing guarantees of title for the time he owned the property (b). This means that Luke is assuring Diana that during the period of his ownership, he has not encumbered the property in any way that would affect her title. Unlike a general warranty deed, which provides a guarantee of clear title from the property's origin, a special warranty deed only covers the timeframe that the grantor (in this case, Luke) owned the property.
