The correct response that identifies new nations created after WWII is North Korea, East Pakistan, and West Germany.
To elaborate:
- North Korea was established in 1948 after WWII, following the division of Korea.
- East Pakistan became a recognized nation following the partition of British India in 1947, which led to the formation of Pakistan with East Pakistan eventually becoming Bangladesh in 1971.
- West Germany (Federal Republic of Germany) was formed in 1949, also as a result of the division of Germany after WWII.
The other options either include countries that were already established prior to WWII or do not fit the criteria for new nations created in the post-war period.
