Solution

The correct option is B Balanced nutrient solution
Hydroponics is the growth of plants in water culture having a balanced nutritional composition depending on the specific requirements of the plants grown. This may also be referred to as soil-less agriculture, test-tube farming, tank farming or chemical gardening.
Commercially, hydroponic cultures are maintained in large shallow concrete, cement wood or metal tanks in which gravel and nutrient solutions are taken. The tanks are provided with pumps and empty auxiliary tanks to pump out and circulate the growth solution and to maintain proper aeration of the nutrient solution.
The technique of hydroponics is employed to know which mineral element is essential for the growth and development of the plant. Commercially the application of hydroponics involves the production of horticultural and floricultural crops.
This method may be used to increase the yield of ornamentals, such as gladioli, snapdragon, roses and vegetables, such as carrot, radish, potatoes, tomatoes and lettuce.
So, the correct answer is 'Balanced nutrient solution'

Bholu wants to grow plants inside his house but he does not like the mess soil makes. So, Bholu uses a technique called hydroponics. In this technique, plants are grown without soil and instead receive nutrients from mineral rich water that is made to flow over the plants roots as shown below. The water needs to be dissolved with chemicals containing plant nutrients such as containing nitrogen, potassium and zinc.

Choose the option that best depicts the relative amount of nutrients that needs to be added to the water. (A bigger circle means more amount and vice versa; if a circle is not present it means that the nutrient is not added ).
