Final answer:
Option (A) is correct: Pollution incidents are generally excluded by the CGL policy, and automobile risks are also excluded. The claim would typically be covered under a Business Auto policy or a specialized environmental insurance policy.
Step-by-step explanation:
The question addresses how a Commercial General Liability (CGL) policy would respond to a claim involving an overturned 18-wheeler that caused a pollution incident. According to the options provided, the correct answer is (A): Pollution, even if sudden and accidental, is excluded by the CGL policy, so the claim is not covered.
This claim also arose out of the operation of the insured's automobile risk, and is also excluded under the GL. Indeed, such incidents require a specialized form of insurance known as environmental insurance or pollution coverage which is separate from a standard CGL policy.
Standard CGL policies have pollution exclusions, except for very specific and limited circumstances, often referred to as sudden and accidental coverage which is still quite restrictive.
Additionally, since the incident involves an automobile, it would typically fall under a Business Auto policy, which is designed to cover liabilities arising from the operation of company vehicles. The correct option is A.
