Answer 1

Hint:- World War II (WWII or WW2) from 1939 to 1945, also remembered as the Second World War, was a global war that held up from 1939 to 1945.
-The immediate cause was due to the attack of the country of origin of the great Nazi leader, Adolf Hitler on its neighboring country where many Jews resided.

Complete answer:
-World War II involved the enormous majority of the globe's countries—including all the great powers—forming two opposite groups: the Allies and the Axis.
Let us examine the options-
-Option A. The Kwantung Army of the Japanese Empire had invaded Manchuria on 18 September 1931. The war ended in February of 1932. It is an incorrect option as WW2 started in 1939.
-Option B. From October 1935 to February 1937 the Second Italo-Abyssinian War was fought between Italy and Ethiopia. It is an incorrect option as WW2 started in 1939.
-Option C. German troops had marched into Austria on March 12, 1938, to annex the German-speaking nation for the Third Reich. In early 1938, Austrian Nazis tried to gain their region and unite their nation with Nazi Germany. It is an incorrect option as WW2 started in 1939.
-Option D. The immediate cause was the intrusion of Poland by Nazi Germany on September 1, 1939, and the ensuing affirmations of battle on Germany made by Britain and France, yet numerous other earlier occasions have been proposed as extreme causes. The political takeover by Hitler led to the idea of the invasion.
-Germany attacked Poland to recapture a lost area and eventually rule their neighbor toward the east. The German invasion of Poland was an introduction to how Hitler expected to take up arms that might turn into the "blitzkrieg" technique.

Based on the above explanation, the correct answer is Option D.

Note:- It was after World War II, The United Nations was set up in October 1945 as a substitution for the League of Nations, to advance global collaboration and forestall struggle. It has been a finished and complete disappointment.
