Final answer:
Coverage B of an H-O policy usually covers separate structures like a swimming pool, not an attached garage or deck which are included in Coverage A.
Step-by-step explanation:
In the context of an H-O policy, which is a type of homeowners insurance, Coverage B generally pertains to structures that are not attached to the main dwelling. Given the options provided, a swimming pool is the one that would typically be covered under Coverage B as it is separate from the house itself. On the other hand, an attached garage or deck that is directly connected to the house would be covered under Coverage A, which is for the main dwelling.
