Dams and reservoirs play a crucial role in:

Irrigation
Hydropower generation
Drinking water supply
All of the above

The correct answer is: d) All of the above

Dams and reservoirs play a crucial role in irrigation, hydropower generation, and drinking water supply.

  • Irrigation is the artificial application of water to land to assist in the growing of crops. Dams and reservoirs can be used to store water for irrigation during dry periods.
  • Hydropower generation is the process of converting the energy of moving water into electricity. Dams and reservoirs can be used to store water and then release it through turbines to generate electricity.
  • Drinking water supply is the provision of water that is safe and suitable for human consumption. Dams and reservoirs can be used to store water that can then be treated and distributed to homes and businesses.

In addition to these three main functions, dams and reservoirs can also be used for flood control, recreation, and fish and wildlife habitat.
