Final answer:
A fee simple estate is the most comprehensive type of property ownership, offering the greatest interest in land that one can possess (a).
Step-by-step explanation:
The most comprehensive estate or tenancy is a fee simple estate. This type of ownership represents the greatest interest in land that can be possessed by an individual, as it is inheritable and does not end upon the owner's death. In contrast, a life estate is limited to the lifespan of a beneficiary; an estate for years is a leasehold interest for a specific, fixed period; and there is no such classification as a free sample estate in the field of property law.
The most comprehensive estate or tenancy is fee simple. Fee simple is the absolute ownership of real property and gives the owner the greatest bundle of rights. The owner can use, possess, lease, sell, or transfer the property without any restrictions.
