In order for a passenger to occupy an exit seat, they must provide which of the following?

The requirement for a passenger to occupy an exit seat is primarily focused on ensuring that the individual is aware of their responsibilities in the event of an emergency. Verbal confirmation is a method used by flight crew members to verify that the passenger understands the situation. This confirmation process allows the crew to engage with the passenger directly, ensuring they understand what is expected of them, which can involve the ability to assist in an evacuation or to respond to crew instructions during an emergency.

This approach is effective because it not only assesses understanding but also confirms that the passenger is willing and capable of assuming the responsibilities associated with being seated in an exit row. While proof of age could be relevant to determine if a passenger is mature enough for these responsibilities, it is not a standalone requirement. Other options such as written confirmation or a signed waiver might provide additional documentation but are not standard practices for confirming the suitability of a passenger for exit seat occupancy. The verbal confirmation serves as both a safety measure and a check on comprehension, making it the appropriate choice in this scenario.
