Explanation:

Douglas MacArthur was a prominent military figure. After World War II, he oversaw the occupation and rebuilding of Japan. In the Korean War, he was the commander of Allied forces. His public criticism of President Truman's handling of the war (such as advocating for an expanded war against China) led to his dismissal. He was not a radio - TV host (first option incorrect). He was not a World War I flying ace involved in the Pusan situation in the described way (second option incorrect). He was not the first ambassador to North Korea (fourth option incorrect).

an ambitious commander of Allied forces in Korea who was dismissed by President Truman for his vocal criticisms of Truman’s handling of the war
