Final answer:
The Bargain and Sale Deed offers the least protection to the buyer, not guaranteeing clear title or freedom from encumbrances, unlike General and Special Warranty Deeds. A Quiet Title Action is not a deed but a legal action to clear title issues.
Step-by-step explanation:
The deed that offers the least protection to the buyer is the Bargain and Sale Deed. This type of deed does not provide any warranty against encumbrances or claim the seller has the right to transfer the title. In contrast, other types of deeds such as a General Warranty Deed offer more protection to the buyer by guaranteeing the seller holds clear title to the property and has the right to sell it, and is thus responsible for any title defects that may arise. A Special Warranty Deed provides some guarantees but only for the period during which the seller owned the property. The Quiet Title Action, often mistaken as a deed, is not a type of deed but a legal action to resolve ownership disputes and clear defects in the title of a property.
