Final answer:
The correct answer is option b) Deed.
Step-by-step explanation:
The document that is used to establish proof of ownership of a property is a deed. An abstract of title is a summary of the history of all legal transactions related to the property. A survey determines the boundaries and dimensions of a property.
A title insurance policy is a contract to compensate the owner or lender for losses in the event the title is challenged or found to be defective. However, the deed is the legal document that is the definitive proof of who owns the property.
