Answer 1

Hint: we know the elements that are required for the soil for the growth of plants. But we are less aware of the elements that are not essential for the soil. It does have the reason for that in a more empathetic way.

Complete Answer:
Firstly, we need to be familiar with the essential minerals for the soil, they are:
Nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel.
In addition to this, there are beneficial elements, which promote the growth of the plant species but are not absolutely necessary for completion of the plant life cycle, or fail to meet certain criteria. Recognised beneficial elements are: silicon, sodium, cobalt, and selenium.
Now the non-essential elements are: according to the given option is vanadium.
Plants may absorb a number of non-essential minerals during the process of their growth. Iodine is one such non- essential element followed by vanadium. It is because of destruction internally or externally done to the process of growth in plants. Due to the side effects of these elements, it is often made sure to check on the growth of plants in order to not affect the growing process of the plants.

Hence, the right option is (D)
