Which cause of loss form provides the broadest coverage for physical loss?

The Special Form provides the broadest coverage for physical loss among the listed options. This form is designed to cover all risks of physical loss or damage to property, except for those specifically excluded in the policy. This means that unless a peril is explicitly stated as not covered, it is included under the Special Form, providing extensive protection.

In contrast, the Basic Form only covers specific, named perils, which means that if a cause of damage isn’t explicitly listed, it is not covered. The Broad Form offers a wider range of coverage than the Basic Form but still includes some exclusions and specific named perils that are not covered. The Earthquake Form is more specialized, covering damage specifically from earthquakes, and does not cover the full range of risks that the Special Form does.

Thus, the Special Form is recognized as the most comprehensive option available for protecting against physical loss, making it the correct choice in this context.
