  • A.Hydrology
  • B.Hydroponics
  • C.Hydril technology
  • D.Hydrophyte

Answer: A

The science is Hydrology.

Hydrology is the science of the waters of the Earth: their occurrence, circulation and distribution, their chemical and physical properties and their relation to the environment. The hydrologic cycle of evaporation, precipitation, infiltration and runoff is its central concept.

Hydroponics is growing plants in nutrient solution without soil. A hydrophyte is a plant that grows in water. 'Hydril technology' is not a branch of science.
