What is a common feature of 'all risk' policies?

The correct choice highlights a defining characteristic of 'all risk' policies, which is their extensive coverage. These policies typically protect against a wide range of potential losses, covering all risks unless they are explicitly excluded in the policy documentation. This stands in contrast to named peril policies, which only provide coverage for specific risks outlined in the policy. Thus, the coverage provided by an 'all risk' policy is broader, as it assumes that anything not specifically excluded is within the scope of coverage.

This aspect of all risk policies is advantageous for policyholders seeking peace of mind, as they do not need to check an exhaustive list of potential covered risks compared to named peril policies. Understanding the nature of exclusions is also critical, as policyholders should carefully review which specific risks are excluded from their coverage to fully grasp what they are and are not protected against.
