A hanging valley is a tributary valley whose floor is significantly higher than the floor of the main valley into which it flows. This occurs when a large glacier in the main valley erodes more deeply than smaller glaciers in tributary valleys. After glacial retreat, the tributary valleys are left "hanging" high above the main valley floor.
Final Answer: Option B - A tributary valley left high above the main valley floor
