Step-by-step explanation:
Eligibility requirements for admission to the Armed Forces Retirement Home are detailed in specific publications that relate to military regulations and federal regulations. Considering the options provided in the question, the correct answer is d. Federal Register. The Federal Register is a daily publication of the U.S. government that communicates proposed and final regulations, including those regarding eligibility for veterans' benefits and retirement facilities such as the Armed Forces Retirement Home.
The Uniform Code of Military Justice (UCMJ) primarily deals with military law and not with admission to retirement homes, while Joint Travel Regulations (JTR) cover travel entitlements for federal employees and military members. A NAVADMIN, or Naval Administrative Message, would not generally contain broad eligibility requirements applicable to all branches of the Armed Forces for retirement homes.
