Final answer:
The major section of the general liability coverage form with a claims-made trigger is Extended Reporting Periods.
Step-by-step explanation:
The one major section of the general liability coverage form that would be found only in a form with a claims-made trigger is C) Extended Reporting Periods.
Extended Reporting Periods (ERPs), also known as tail coverage, are provisions in claims-made liability insurance policies that allow the insured to report claims after the policy period expires. In claims-made policies, coverage is triggered by the reporting of a claim during the policy period or within a specified extended reporting period.
For example, if a claims-made general liability policy has a one-year policy period and a 60-day extended reporting period, the insured has 60 days after the policy expires to report a claim that occurred during the policy period.
