Hydroponics is the technique by which plants are grown in water without soil.
B
Correct answer
Explanation
The statement correctly defines hydroponics. Hydroponics is indeed a soilless cultivation method where plants grow in nutrient-rich water solutions. The technique allows plants to absorb essential minerals and nutrients directly from water, with their roots supported by inert growing media or suspended in the solution itself. This method is widely used in modern agriculture for efficient food production.
