What Causes of Loss form is attached to a commercial property policy that provides named-peril coverage?

The Basic Form is the correct choice because it outlines specific named perils that are covered under a commercial property policy. Named-peril coverage means that only the perils explicitly listed in the policy are covered. The Basic Form typically includes a limited set of perils, such as fire, theft, explosion, and vandalism, providing a straightforward approach to insuring property against certain risks.

In contrast, the Broad Form includes additional perils beyond those in the Basic Form, offering a more expansive coverage but also elevating the complexity and potential cost of the policy. The Special Form, on the other hand, generally provides an "all risks" type of coverage, meaning it covers all perils except those specifically excluded in the policy. The All Risk Form is similar to the Special Form and also involves expansive coverage, leaving only specifically excluded items unprotected.

Focusing on the nature of the coverage offered, the Basic Form specifically fits the definition of named-peril coverage, making it the correct option to choose in this context.
