Final answer:
A fixture is former personal property that automatically conveys with real property upon its sale. It is different from chattel, which is movable, trade fixtures, which are used for business in a leased space, and accession, which is an addition that does not always convey automatically.
Step-by-step explanation:
The question relates to the legal concept of which type of property automatically becomes part of real property upon attachment. The correct answer is B) Fixture. A fixture is a piece of former personal property that has been so annexed to real property that it is legally considered part of that real property. This usually occurs when personal property, such as a built-in bookcase, is securely and permanently attached to a house or building. When the real property is sold, the fixtures are included in the sale, automatically conveying with the property.
On the other hand, A) Chattel refers to personal property that is movable and does not automatically convey with real property. C) Trade fixture pertains to property attached to a leased space by a tenant for business purposes, which can often be removed at the end of a lease. And D) Accession refers to something that is added to property that already belongs to a person, which may also become part of the real property, but does not always do so automatically.
