Which type of property is defined by its movability?

The correct choice is personal property, which is defined by its movability. Personal property encompasses items that are not permanently attached to or part of the land. This category includes tangible items such as furniture, vehicles, equipment, and other belongings that can be relocated from one place to another without causing damage to the land itself.

In contrast, real property refers to land and any structures or improvements attached to it, which are fixed in place and not moveable. Natural property is not a standard classification in property law; it may refer generally to resources like minerals or vegetation but does not define a type of property based on movability. Fixed property generally signifies immovable property, which again points to real estate. Therefore, personal property is the type distinctly characterized by the ability to be moved.
