C Correct answer
Explanation

Hydroponics is the soilless cultivation of plants where roots grow in nutrient-rich water solutions or inert media like perlite or rockwool. The term comes from Greek 'hydro' (water) and 'ponos' (labor). It's not about aquatic plants in general (options A, B, D) but rather a controlled agricultural technique for growing terrestrial plants without soil.
