Step-by-step explanation:
When offered a gift from a source outside of the Department of the Navy, the appropriate response would be to decline politely. This is because accepting the gift could create a conflict of interest or be seen as an attempt to gain favor or influence. It is important to maintain impartiality and avoid any perception of impropriety.
Reporting immediately would also be necessary to ensure transparency and adherence to ethical standards. By promptly reporting the offer of the gift, proper actions can be taken, such as rejecting the gift, if necessary, and addressing any potential concerns.
