Which mostly accurately identidies the relationship bewteen aemistic day and veterans day

Option d, both Armistice Day and Veterans Day involve honoring veterans, however, Armistice Day was replaced by Veterans Day after the end of World War I.

Explanation

Veterans Day is observed on November 11 every year to recognize the services of that army personnel who worked in the United States Armed Forces and were discharged subsequently. This day is commemorated to display respect, regard, and honor and appreciate the hard work of the stalwarts in the uniform who risked their lives for the betterment and safety of the people of the country. The good thing about this day is that it also remembers those individuals in the military who are deceased and have either laid down their lives for the country or are have passed away for other reasons.

Veterans were initially called the Armistice Day and was first to  observed on November 11, 1919, to mark the end of World War I, however, the United States under the leadership of President Dwight Eisenhower in 1954 changed it's name to veterans day.

The idea to convert the name of armistice day to veterans day so to render more inclusivity in its observance where not only military personnel but also all veterans would be included in recognizing their services. It is for this reason perhaps there is no apostrophe in the word veteran - we express it as Veterans Day and, not veteran's day.
