The correct response is:
North Korea, East Pakistan, and West Germany
These nations were created or emerged in the aftermath of World War II. North Korea was established in 1948. East Pakistan became Bangladesh in 1971, but it was recognized as a separate entity upon the partition of India in 1947. West Germany (officially the Federal Republic of Germany) was also created in 1949, following the division of Germany after the war. The other options contain countries that do not fit the criteria of being newly created nations after WWII.
