The correct Answer is:
**Step-by-Step Solution:**
1. **Understanding Hydroponics**: Hydroponics is a method of growing plants without soil. Instead of soil, plants are grown in a nutrient-rich water solution.
2. **Definition**: The term "hydroponics" comes from the Greek words "hydro" meaning water and "ponos" meaning labor. Thus, it literally means "water working."
3. **Cultivation Method**: In hydroponics, the roots of the plants are submerged in a nutrient solution, which provides all the essential nutrients that plants need for growth.
4. **Soil-less Culture**: Since hydroponics does not use soil, it is referred to as a soil-less culture. This method can lead to faster plant growth and higher yields compared to traditional soil-based growing methods.
5. **Conclusion**: The correct answer to the question "Hydroponics is" is that it is a method of growing plants in a nutrient solution without soil.
**Final Answer**: Hydroponics is the cultivation of plants by placing their roots in a nutrient solution without soil.
