Hydroponics refers to growing plants in which medium?

Explanation:
Hydroponics is growing plants with a nutrient-rich water solution rather than through soil. The roots receive minerals dissolved in water, and an inert growing medium may be used only to support the plant, not to supply nutrients. That’s why the described choice—water containing dissolved nutrients, without soil—best fits hydroponics. The other scenarios involve soil-based nutrition, growing roots in air, or using a medium without nutrients, none of which define hydroponics.
