Final answer:
The perpetual estate with no usage restrictions is known as a fee simple absolute, which grants complete ownership with no conditions that could void the property's ownership. Option b.
Step-by-step explanation:
Of the two kinds of fee simple estate, the kind that is a perpetual estate with no usage restrictions is the (B) fee simple absolute. This type of estate is the most complete form of ownership that one can have in real property. Unlike a fee simple defeasible or fee simple determinable, which have conditions or terms that could cause the ownership of the property to be void, a fee simple absolute has no such limitations or conditions. It is an unconditional and inheritable estate in land that lasts until the current holder of the property dies without heirs.
