D a demilitarized zone

D. a demilitarized zone

The correct answer is D) a demilitarized zone.

To find the answer to this question, one can start by understanding the geography and history of the Korean Peninsula. The Korean Peninsula is located in Northeast Asia, with North Korea occupying the northern half and South Korea occupying the southern half.

Historically, Korea was a single unified kingdom up until the late 19th century. However, after the end of World War II in 1945, Korea was divided into two separate countries, North Korea and South Korea.

To maintain the separation between the two countries, a demilitarized zone (DMZ) was established along the 38th parallel, which served as the border between North Korea and South Korea. The DMZ is a strip of land that runs across the region and acts as a buffer zone between the two countries.

The DMZ stretches about 250 kilometers (155 miles) from east to west and is approximately 4 kilometers (2.5 miles) wide. It is heavily fortified and guarded, with barbed wire, landmines, and military personnel from both countries stationed along the border.

Therefore, the correct answer is D) a demilitarized zone, which separates North Korea and South Korea.
