Explanation:

In the context of World War I trench systems, the zig - zagging trenches (including those on both the Western and other fronts) had a total length of about 25,000 miles. The other options (3000 miles and 250 miles) are too short to represent the extensive network of trenches.

Answer:

25,000 miles
