Which of the following is NOT a category of personal property?

The correct answer is 'Sustainable' because it does not represent a recognized category of personal property. In property management and accountability, personal property is typically classified into three main categories: expendable, durable, and nonexpendable.

Expendable items are those that are consumed or depleted during use, such as office supplies or food. Durable items are those that have a longer life span and can be used for multiple purposes, like furniture or equipment. Nonexpendable property refers to items that are not intended to be consumed, and typically remain in use for an extended period, requiring careful tracking and accountability.

'Sustainable' is related more to environmental practices and ensuring resources are used in a way that maintains ecological balance, rather than a classification of personal property in accountability contexts. It does not align with the established categories used in inventory and property management systems.
