Which of the following describes a trade fixture?

A trade fixture is defined as an item that is attached to a commercial property for the purpose of conducting business, and it is essential to the tenant's trade or business operations. The distinguishing characteristic of a trade fixture is that, unlike regular fixtures, which are generally considered permanent additions to real property, trade fixtures remain the personal property of the tenant. Upon lease termination, the tenant typically has the right to remove these fixtures, as they are integral to the nature of the tenant's business.

This concept helps clarify the nature of items that serve specific business functions while simultaneously being affixed to the leased property, emphasizing the tenant's ownership rights over these items. In contrast, the other options focus on permanent fixtures or items not directly related to a tenant's business, thus highlighting the unique nature of trade fixtures in commercial leases.
