B Correct answer
Explanation

The Great Wall of China is the largest wall in the world by total length and construction effort. While the Korean Demilitarized Zone has fortifications, and ancient walls like the Anastasian and Aurelian Walls exist, none compare to the Great Wall's scale of over 21,000 km of wall structures built over centuries.
