Final answer:
Any member of the Armed Forces of the United States who dies on active duty, or veteran with a discharge other than dishonorable, is authorized a US flag over their casket. This extends to members with certain conditions in the Reserve, National Guard, Public Health Service, and NOAA. Therefore, the answer is all military personnel, veterans, and first responders with qualifications.
Step-by-step explanation:
The question: Who is authorized to have a US flag over their casket at a military funeral, can be addressed with the following information. The United States Department of Veterans Affairs states that any member of the Armed Forces of the United States who dies on active duty, as well as any veteran who was discharged under conditions other than dishonorable, has the right to have an American flag draped over their casket. This right is also extended to certain other groups, such as Reserve and National Guard members entitled to retired pay, former members eligible for retired pay but who are not yet age 60, and members of the Commissioned Officer Corps of the Public Health Service and National Oceanic and Atmospheric Administration.
It is not exclusively for Medal of Honor recipients or only for those of a certain rank, and it includes more than just first responders. The tradition of draping a flag over the casket is a way to honor the deceased's service to their country. So, the correct answer to the student's question would be: d) All military personnel, veterans, and first responders under certain conditions.
