Correct Answer: soil
Solution : The correct option is soil.
Hydroponics is a plant cultivation technique that does not require soil as a growing medium. Instead, a nutrient-rich water solution is used to supply critical minerals and nutrients straight to the plant roots. This approach enables regulated and efficient plant development, allowing crops to be grown in soil-free environments, frequently in a controlled indoor setting.
