If a project trailer is vandalized, which type of insurance would cover the claim?

The correct choice in the event of vandalism to a project trailer is property insurance. Property insurance is designed to cover damage or loss to physical assets, including buildings, equipment, and trailers owned or used by the project. This type of insurance specifically protects against a variety of risks not just limited to external disasters, but also includes theft and vandalism.

Vandalism falls under the category of property damage insurable by property insurance, which is why this policy would typically provide the necessary coverage for a claim related to such an incident. Each of the other options serves different purposes and would not provide adequate coverage for damage resulting from vandalism. For instance, errors and omissions insurance addresses liability arising from professional mistakes, builder's risk insurance covers losses related to the construction process itself (primarily during construction), and general liability insurance covers claims of bodily injury or property damage occurring during operations, but does not include specific protection for vandalism to property.
