Final answer:
Group Accidental Death and Dismemberment (AD&D) Insurance is the type of insurance that best describes a policy against injury resulting from accidents, covering a group of persons. So, the correct answer is option 2.
Step-by-step explanation:
The policy or contract of insurance against injury resulting from an accident or accidental means that insures a group of persons is best described by Group Accidental Death and Dismemberment (AD&D) Insurance (Option 2).
This type of insurance provides benefits to the insured group in the event of accidental death or dismemberment. It is different from Group Health Insurance, which covers medical expenses, Group Disability Insurance, which provides income in the event of disability due to illness or injury, and Group Term Life Insurance, which provides a death benefit to beneficiaries if the insured dies during the term of the policy.
