Which of the following objects is defined as personal property?

Personal property refers to movable items that are not permanently attached to land or a structure. Among the options given, a kitchen table qualifies as personal property because it is not fixed in place and can be moved freely.

Conversely, a tree in a backyard is considered real property because it is permanently rooted in the ground. A built-in cabinet is also classified as real property since it is attached to the structure of the home, making it a permanent fixture. A driveway, while it may seem separate, is considered part of the real property as it is a permanent feature of the land.

Therefore, the kitchen table stands out as the only item in the list that meets the criteria for personal property, being movable and not permanently affixed to any real estate.
