The Terrorism Risk Insurance Program Reauthorization Act of 2015 excludes all of the following, EXCEPT:

The Terrorism Risk Insurance Program Reauthorization Act of 2015 provides a federal backstop for insurance claims related to acts of terrorism. Under this law, certain types of properties and items are excluded from coverage.

Commercial property falls within the scope of potential coverage provided by the Act, as it is generally included in the definitions of eligible risks that can be covered by terrorism insurance. This means that if a terrorist attack were to cause damage to commercial property, those losses could be covered under the federal program, assuming the policy in place includes terrorism risk.

In contrast, government property, residential property, and luxury items are specifically excluded from this program. This means that any losses resulting from acts of terrorism affecting these types of properties or items would not be eligible for federal assistance or coverage under this particular law.

Therefore, commercial property is the correct answer, as it remains included in the coverage provisions of the Terrorism Risk Insurance Program, whereas the other options are not eligible for benefits under this Act.
