What type of form is attached to a property insurance policy to clarify which perils are covered?

The Cause of Loss Form is the correct choice because it specifically outlines and clarifies the perils that are covered under a property insurance policy. This form delineates the risks included in the policy such as fire, theft, or water damage, providing the policyholder with clear information on what is protected.

The Declarations provide essential details about the policy, such as the insured property's address, the policyholder's name, and the limits of coverage, but do not specify which perils are covered. On the other hand, Coverage Forms, while somewhat related, outline the types of coverage (like liability or property coverage) but may not detail the specific perils as clearly as the Cause of Loss Form does. Lastly, Conditions refer to the duties and responsibilities of the insured and insurer within the contract, rather than the specific perils covered by the policy.
