Which of the following would be covered under Coverage A in a dwelling policy?

Coverage A in a dwelling policy typically encompasses the structure itself and attached fixtures. This includes the primary dwelling and any built-in systems that contribute to the home's function and safety, such as heating systems.

The gas furnace, being an integral component of the dwelling's heating system, falls under this coverage because it is attached to the property and essential for maintaining a habitable environment. In the context of a dwelling policy, Coverage A is designed to protect against damage to the home's structures and systems that are fixed and immovable.

In contrast, while an outdoor swimming pool or a detached garage may hold value, they are often considered separate structures or personal property and may be covered under other sections of a policy or with specific endorsements. The swimming pool heater, while important, is not as directly associated with the primary dwelling itself as the gas furnace is, which serves a crucial function within the home.
