Why are hydroelectric power plants and dams often located in mountainous areas?

Question 12 options:

Hydroelectric power plants and dams are not located in mountainous areas.

Human population in the mountains is less than elsewhere, so it is easier to find places to build the power plants.

Water is only available in the mountains, so any hydroelectric power plants have to be located there.

The downward flow of water is what generates energy and mountains have streams flowing downward.
