Which of the following is an example of an extra expense that is covered without requiring business income coverage?

An example of an extra expense covered without requiring business income coverage is equipment rental. In the context of insurance policies, particularly those related to business interruption, extra expenses are often defined as costs that a business incurs to maintain its operations during a period of loss or downtime. Equipment rental helps businesses continue functioning and generating income when normal operations are interrupted, such as after a fire or a natural disaster.

Equipment rentals are necessary to replace or supplement the equipment that was damaged or destroyed, allowing businesses to minimize their losses and adapt quickly to unforeseen circumstances. This is distinct from other types of expenses related to ongoing operations. Operational expenses, worker salaries, and inventory purchases are typically associated with maintaining the daily functioning of the business rather than with mitigating losses specifically during periods of interruption. As such, they would not fall under the category of extra expenses covered explicitly in this context.
