Answer :
The end of Japanese colonization of the Korean peninsula had a significant outcome that d) the peninsula was split into two nations.
When World War II ended in 1945, Korea was liberated from Japanese rule. However, instead of establishing a unified Korea, the peninsula was divided along the 38th parallel. The northern part was occupied by Soviet troops, who established a communist government, while the southern part was occupied by American forces, who supported a non-communist regime.
This division eventually solidified into two separate countries: North Korea and South Korea. This split laid the groundwork for major historical events, including the Korean War in the early 1950s and ongoing tensions between the two nations.
