Which of the following marks a tribute to military veterans?

Veterans Day specifically honors and pays tribute to military veterans who have served in the United States Armed Forces. It is a day set aside to recognize and express appreciation for the sacrifices and contributions of those who have served in the military. The observance of Veterans Day came into effect following World War I, originally observed as Armistice Day on November 11th, commemorating the end of the war. In 1954, it was renamed Veterans Day to honor all veterans, not just those who fought in World War I.

In contrast, Independence Day celebrates the nation's declaration of independence from British rule, Thanksgiving is a holiday focused on giving thanks and the harvest, and Labor Day celebrates the contributions of workers and the labor movement. While these other holidays may acknowledge aspects of American history and culture, they do not specifically pay tribute to military veterans in the way that Veterans Day does.
