Final answer:
The party receiving the ownership rights is called the remainderman.
Step-by-step explanation:
The correct answer is c) Remainderman. When title passes upon the death of a life tenant to a party other than the original grantor, the party receiving the ownership rights is known as the remainderman. The remainderman is a person who has a future interest in a piece of property, and their ownership rights will only become possessory upon the death of the life tenant.
