What does "marketable title" refer to?

Marketable title refers to a title that is free from significant defects, allowing it to be easily sold or mortgaged without any encumbrances that could cause legal issues in the future. This concept is crucial because property buyers and lenders need assurance that the title is clear and will not face challenges from other claims, liens, or disputes. A marketable title provides confidence in the ownership rights of the property, ensuring that the buyer can take possession without worry of future legal entanglements.

While historical significance, exclusivity to commercial properties, or temporary status may pertain to certain types of titles or contexts, they do not define marketable title. Therefore, the emphasis on clarity and the ability to transfer ownership smoothly is what makes option A the correct choice.
