Which of the following cannot be buried in a national cemetery?

In national cemeteries, the eligibility for burial is primarily focused on individuals who have served in the military and their immediate family members. Active-duty officers or members of the armed forces typically have guaranteed burial rights in these cemeteries as they are the primary individuals who have served.

Spouses and widows of members of the armed forces are also entitled to burial in national cemeteries, as they are regarded as immediate family and survivors of those who served. Minor children of any service member are generally included in the eligibility criteria for burial as well.

Parents of a member of the armed forces, however, do not have the same burial benefits in national cemeteries. While they may be able to be interred in certain situations, they are not automatically eligible for burial in a national cemetery simply by virtue of being a parent. This distinction highlights the focus on service members and their immediate dependents rather than extending burial eligibility to additional relatives.
