Which of the following is a feature often found in group life insurance policies?

Group life insurance policies are characterized by their structure of providing coverage to multiple individuals under a single contract, often facilitated by employers or organizations. This means that the coverage is generally provided as a benefit to employees or members, which makes it more accessible and cost-effective for individuals compared to individual life insurance policies.

Option D highlights this key feature, as the policy typically serves a group... like employees at a company or members of an organization, allowing for streamlined administration and often more favorable terms compared to individually purchased policies.

The other options describe features not commonly associated with group life insurance. Individual medical underwriting is generally a characteristic of individual life insurance policies, where each applicant's health is evaluated separately. High premiums relate to the costs associated with individual policies, which are usually more expensive than the group rates provided through employer-sponsored plans. Lastly, coverage concentration among a specific age group doesn’t reflect the broad and inclusive nature of most group policies, which aim to provide availability to a diverse range of ages within the covered group.
