Which of the following is covered under the general property policy form?

The correct choice is commercial structures because the general property policy form is specifically designed to provide coverage for a wide range of property types used for business purposes. This includes buildings, equipment, inventory, and other physical assets associated with commercial operations.

The general property policy typically covers risks such as fire, theft, and other perils that might cause damage to commercial properties. It accommodates various forms of business real estate, making it a fit for commercial structures.

In contrast, residential homes are usually covered under homeowners insurance policies, which address the unique needs and risks associated with personal residences. Landscaped properties, while they may have some specific coverage under property policies, generally require specialized coverage for risks associated with landscaping. Private vehicles fall under auto insurance policies tailored to address the specific risks associated with vehicle ownership and operation, rather than being covered by property policies.
