The correct answer is D. All of the above.
Water resources are essential for human life and economic activity. Areas with abundant water resources, such as rivers, lakes, and groundwater, are more likely to be populated than areas with limited water resources.
Topography also affects population distribution. Areas with flat terrain are more easily accessible and developed than areas with rugged terrain. This is why most of the population of Telangana is concentrated in the plains of the Godavari and Krishna rivers.
Economic opportunities are another important factor in population distribution. People are more likely to live in areas where there are good job opportunities and a strong economy. Telangana is a rapidly developing state with a growing economy, which has attracted people from other parts of India.
In conclusion, all of the factors mentioned in the question affect population distribution in Telangana.
