Hanging valleys are formed by the action of:
A
Moving ice
B
Wind
C
Running water
D
None of these
Explanation: 

Detailed explanation-1: -waterfalls are most common where hanging valleys occur. Such valleys generally form when glacier ice deeply erodes a main or trunk valley, leaving tributary valleys literally hanging far above the main valley floor.

Detailed explanation-2: -A former tributary glacier valley that is incised into the upper part of a U-shaped glacier valley, higher than the floor of the main valley. Hanging valley streams often enter the main valley as waterfalls.

Detailed explanation-3: -A hanging valley can be formed when the lower valley has a greater rate of erosion. This can be cause by 2 glacier flows, one feeding the other. This may also be caused by a greater flow of water in the lower valley or soft rock layers that erode more quickly.

Detailed explanation-4: -A hanging valley is a sub valley which is higher than the main valley. They are related to U shaped valley when any sub glacier is flown into a large glacier. Hence Hanging valleys are formed due to the action of Glacier.

Detailed explanation-5: -Thus, hanging valleys are formed as a result of the erosion effects due to glaciation. Research says that the valleys are formed because of two different glaciers. These glaciers interact with each other and ultimately lead to the process of the formation of hanging valleys.
