Step-by-step explanation:
The statement that best explains why instruments affecting real estate, such as deeds or easements, are recorded in the register of deeds in the county where the property is located is to establish a chain of title and provide public notice.
Recording these instruments ensures that there is a public record of all legal documents pertaining to a property, which is vital for maintaining an accurate property title, necessary in transactions like selling farmland for development.
Additionally, this process helps delineate property lines and prevent disputes over land use that could be caused by non-government restrictions like restrictive covenants and easements.
