The correct answer is: b) Remote villages
Arunachal Pradesh is a state in northeastern India. It is the largest state in the country by area, but has the lowest population density. The state is home to a number of different ethnic groups, and many of its villages are located in remote areas.
Small and micro-hydropower projects can provide a reliable source of electricity to these villages. They are also relatively inexpensive to build and operate, and they do not produce any emissions.
Option a) is incorrect because major cities already have access to electricity from the grid. Option c) is incorrect because industrial areas are typically located near major cities, and they already have access to electricity from the grid. Option d) is incorrect because neighboring states already have access to electricity from the grid.
In conclusion, Arunachal Pradesh has potential for small and micro-hydropower projects to provide electricity to remote villages. These projects can provide a reliable source of electricity, and they are relatively inexpensive to build and operate.
