Final answer:
Inland marine insurance covers movable property in transit or not fixed to a specific location, but not permanently fixed items like telephone lines.
Step-by-step explanation:
Inland marine insurance is a type of insurance that covers property in transit or property that is not fixed to a specific location. It is typically used to cover goods and equipment while they are being transported over land. Inland marine insurance can cover a wide range of items, including construction equipment, tools, and artwork.
In the context of this question, inland marine insurance covers pipelines, bridges, and watercraft because they are movable and are not permanently fixed to a specific location. However, it does not cover telephone lines because they are usually permanently fixed and do not qualify for this type of insurance.
