In which section of an insurance policy does an insurer provide details of different sums insured under the policy?

The correct choice is the policy schedule, as this section of an insurance policy outlines specific details relevant to the insurance contract, including the different sums insured for each section of coverage. It serves as a summary of the terms, conditions, and details agreed upon by the insurer and the insured, allowing the insured party to see at a glance the amounts covered for various types of risks.

The policy schedule is essential because it breaks down the extent of coverage, limits, and deductibles applicable to different aspects of the policy, all of which are crucial for the policyholder to understand their protection limits.

On the other hand, while the heading identifies the type of policy and the parties involved, it does not provide specifics about coverage amounts. The operative clause outlines the terms under which the insurer will provide coverage but does not give the specific sums insured. Similarly, the preamble typically contains the introductory statements and describes the nature of the contract but lacks the detailed financial coverage information that the policy schedule specifically provides. Thus, for clarity on sums insured, the policy schedule is the vital resource.
