B Correct answer
Explanation

Jakobshavn Glacier in Greenland moves at approximately 40-50 meters per day, which equals about 8-12 miles (12,600-19,000 meters) per year. This makes it one of the fastest-flowing glaciers on Earth. The speed has increased significantly due to climate warming and ice sheet thinning. The 8-mile (12,600 meters) figure represents a reasonable annual speed estimate for this rapidly moving outlet glacier.
