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 plant's roots as shown below. The water needs to be dissolved with chemicals containing plant nutrients such as nitrogen, potassium, and zinc.
Choose the option that best depicts the relative amount of nutrients that need to be added to the water. (A bigger circle means more amount and vice versa; if a circle is not present, means that the nutrient is not added ).

The correct option is C
Carbon, Oxygen and Hydrogen are needed in large quantities by the plant. But these three elements are obtained from carbon dioxide and water. Thus these are not added to the water.
The other nutrients are absorbed from the soil. These include Nitrogen (N), Potassium (K) and Phosphorous (P), zinc, magnesium and selenium. The NPK nutrients are needed in larger quantities compared to elements such as zinc. NPK nutrients are called macronutrients for this reason. Nitrogen is also a major component of amino acids, the building blocks of proteins. Thus, compared to Zinc, Nitrogen and Potassium is needed in a relatively large quantity. Hence option C is correct.
