Which deed provides the least amount of protection?

The quitclaim deed offers the least amount of protection because it is essentially a transfer of whatever interest the grantor has in a property without any guarantees or warranties regarding the title. This means that the grantor does not imply any assurance that the title is clear or that they even have the legal right to convey the property.

In contrast, a warranty deed provides the highest level of protection, as it guarantees that the grantor holds clear title to the property and is responsible for defending it against any claims. A grant deed offers some level of assurance, typically ensuring that the property has not been sold to someone else and that there are no undisclosed encumbrances. A foreclosure deed, which is used in the process of foreclosure, typically transfers ownership to the foreclosing lender but may come with specific implications about the title depending on the situation.

Given these definitions, the quitclaim deed is the least protective form of conveyance, as it provides no assurances regarding the title status, making it the correct answer.
