The correct answer is B) adverse possession, which is a form of involuntary alienation where ownership of property is transferred without the owner's consent. This occurs when a person occupies land for a certain period of time under specific legal conditions. Other options like a mortgage or a deed involve voluntary agreements, while blockbusting is not a legal form of alienation.
