Which of the following is not classified as real property?

Trade fixtures are items installed by a tenant in a commercial property for conducting business. Although they are attached to the real estate, they are considered personal property because they are typically removable by the tenant when the lease ends. In contrast, land, improvements to the land (such as landscaping or infrastructure), and buildings are classified as real property because they are permanent or semi-permanent fixtures that are considered part of the property and transfer with ownership. Therefore, trade fixtures represent a unique situation where attachments made for business purposes retain a personal property classification rather than being classified as real property. This distinction is important for both landlords and tenants to understand, especially in the context of property rights and leases.
