Hint:Fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants.

Complete answer:
Fertilizers are chemical substances supplied to the crops to increase their productivity. These are used by the farmers daily to increase the crop yield. The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium, and phosphorus.

Now let’s see what is the full form of chemical fertilisers NPK,

The first option for k is given calcium but k stands for potassium, therefore this could not be the answer.
N is for Nitrogen not for nitric acid, and K is for potassium not for calcium therefore this also could not be the answer.
NPK stands for "nitrogen, phosphorus, and potassium," the three nutrients that compose complete fertilizers.
Here N is given for nitric acid therefore this could not be the answer.

Therefore the correct answer is C. Nitrogen Phosphorus and Potassium.

Note:The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium, and phosphorus.The fertilizer definition can not specifically say “NPK,” but at least you can see three numbers in a row. These numbers refer to the nitrogen content, phosphorus and potassium content of the fertilizer, respectively. A percentage symbol after each number is also inferred since each of the three numbers reflects the percentage of that nutrient in the fertilizer’s composition.
