Final answer:
Fixtures are treated as real property and are not removable by a tenant before or after the expiration of the lease.
Step-by-step explanation:
A fixture refers to an item that is attached or affixed to real property and is treated as part of the property. It is not considered to be movable personal property or chattel, but rather it is considered to be real property.
Examples of fixtures include things like built-in shelves, light fixtures, and plumbing fixtures. These items are typically permanently attached to the property and are not intended to be easily removed or taken by a tenant.
Therefore, the correct answer to the question is A. Fixtures are treated as real property and are not removable by a tenant before or after the expiration of the lease.
