Final answer:
A judgment lien (D) is classified as a general lien because it can attach to all of the debtor's property, unlike specific liens such as mechanics liens and real estate property tax liens which attach to specific property.
Step-by-step explanation:
The question asks which of the given options would be classified as a general lien. A general lien is a legal claim against all the property of a debtor, as opposed to a specific piece of property.
Of the options provided, the answer is D. a judgment lien. Mechanics liens and property tax liens, such as real estate property tax liens, are specific liens because they are claims against specific properties. Judgment liens, however, are typically general liens because once they are recorded, they can attach to all the debtor's property, including property acquired after the lien is in place.
