To whom can the CO delegate 2 spot checks at the command?

The correct answer is that the Commanding Officer (CO) can delegate spot checks to the Executive Officer (XO). This is because the XO typically holds a position that is directly below the CO and is responsible for executing the CO's orders, managing the day-to-day operations of the command, and assuming command in the CO's absence. Delegating responsibilities such as spot checks to the XO ensures that oversight mechanisms are in place, while the CO can focus on broader strategic issues.

The other roles mentioned, like the Deputy CO, Senior Enlisted Advisor, and Command Chief, may have different responsibilities and levels of authority within the command structure, but the XO is specifically trained to support the CO in a range of operational duties, including conducting inspections and ensuring compliance with policies. Therefore, the delegation of such tasks fits squarely within the XO's responsibilities and authority.
