Correct Answer: (a) Growing plant without soil

Solution:Hydroponics is a subset of hydro culture and is a method of growing plants using mineral nutrient solutions in water without soil. Hydroponics, also known as soilless cultivation, offers a versatile approach to plant cultivation, suitable for various applications. In this technique, plants are grown with their roots exposed to a nutrient-rich water solution, or they may be supported by an inert medium like perlite or gravel. The nutrient solution provides plants with the essential elements they need for growth, including water, oxygen, and dissolved mineral salts.
