The correct option is C soil
The technique of growing plants in a soil-free nutrient solution is called hydroponics. The technique was first demonstrated by Julius Von Sachs in 1860. In this technique, plants are grown in a nutrient solution containing minerals required for the growth of plants. The nutrient solution has to be constantly aerated for the proper growth of the plants. Hydroponics is successfully used these days for the commercial production of tomato, seedless cucumber, lettuce, etc.
