Which of the following is NOT a category of the Nationwide Marine Definition?

The correct answer identifies a category that falls outside the scope of the Nationwide Marine Definition, which is a standardized framework used primarily to categorize various types of marine and related insurance.

Private passenger autos do not fall under this definition as they are typically categorized under automobile insurance, not marine insurance. The Nationwide Marine Definition primarily encompasses risks associated with marine activities and property that is inherently portable or has a relationship to transportation, such as personal watercraft and baggage.

Commercial property is also included in the marine definition as it pertains to property related to marine operations, while personal watercraft and baggage fit into the categories of goods and property commonly insured under marine policies. Thus, private passenger autos are distinctly outside the marine insurance context, making it the correct answer.
