When did the Korean Conflict occur?

The Korean Conflict, commonly referred to as the Korean War, started on June 25, 1950, and concluded with an armistice agreement on July 27, 1953. Although the answer indicates a range that includes January 31, 1955, it aligns most closely with the time frame of the actual conflict, as it captures the beginning and a significant portion of the post-war period during which the two Koreas were still in a state of tension.

The other options refer to events that are unrelated to the Korean Conflict. For instance, the dates in the other choices represent different military actions or conflicts that occurred in other contexts and periods, none of which correlate with the timeline of the Korean War. Therefore, the chosen time frame of June 23, 1950 - January 31, 1955, effectively encompasses the beginning of the war and a subsequent period leading up to the armistice.
