Which of the following adds additional perils such as weight of snow?

The answer is D because the Broad Form policy is designed to cover a wider range of risks compared to the Basic Form policy. Basic Form policies typically only cover certain listed perils, such as fire, theft, or vandalism, without including additional risks like damage caused by the weight of snow. In contrast, the Broad Form policy expands the coverage by adding various other perils, including but not limited to the weight of snow, falling objects, and water damage from damaged appliances.

This additional coverage helps protect policyholders from a broader spectrum of potential damages that can occur, which is particularly important in regions where heavy snowfall can impact the structure of buildings. The Special Form, while also comprehensive, generally covers all risks except those specifically excluded, which might lead to confusion regarding perils, but it is more aligned with coverage for unusual causes rather than specifically adding common perils such as snow weight. The Comprehensive Form is not a specific terminology typically used in insurance for property coverage, thus making Broad Form the most accurate choice in this context.
