Which of the following would be covered by inland marine insurance?

Inland marine insurance primarily covers a wide range of movable property and specialized types of risks associated with transportation and communication. Among the listed options, bridges fall within the scope of inland marine insurance because they can be considered transportation-related structures. They support the movement of goods and people, linking different areas and facilitating commerce, which aligns with the purpose of inland marine coverage.

This type of insurance typically covers not only vehicles but also cargo being transported, equipment, and certain types of property that are mobile or used in transit. Inland marine policies are designed to protect these assets from risks such as theft, damage, or loss while they are in transit or in specific locations away from their permanent location.

In contrast, the other options either pertain to standard property coverage or fall outside the typical definitions associated with inland marine coverage: motor vehicles are generally covered under auto insurance, personal property at home is typically covered by homeowners insurance, and business liability refers to coverage related to legal claims against a business for damage or injury, which isn't within the scope of inland marine policies.
