Choose the correct answer from the alternatives given.
Hydroponics is a technique of growing:

  1. submerged Plants
  2. free-floating aquatic plants
  3. terrestrial plants in sand
  4. plants in aqueous balanced nutrient medium
Correct Answer: Option(d)
Solution: Hydroponics is a subset of hydroculture, which is a method of growing plants without soil by using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. So, the correct answer is "plants in the aqueous balanced nutrient medium".
