Final answer:
Inland marine insurance covers risks such as domestic shipments, and cargo for export but not commercial autos, which are instead covered by commercial auto insurance. The correct answer is option 4.
Step-by-step explanation:
According to the Nationwide Marine Definition, the risks that may be insured by inland marine insurance typically include domestic shipments, cargo being transported for export, and transmission towers and their equipment. However, commercial autos are not covered by inland marine insurance as they are generally covered by their own specific type of insurance, known as commercial auto insurance. Inland marine insurance is designed to cover property that is on the move or in transit, as well as unique or high-valued items that traditional property insurance may not cover, hence its coverage generally aligns with the transportation of goods and equipment, and not vehicles used for transportation.
