Hint: Different elements have various different roles in the growth of plants like potassium is responsible for regulating the water content in plants, and it is sometimes required in higher amounts even than nitrogen. Also potassium is used in the manufacturing of fertilizers that are also needed for plant growth.

Complete answer:
There are two most crucial elements that are useful in the growth of plants and these are Nitrogen and Phosphorus. Both these elements are non metals. Nitrogen helps in the development of leaves in a plant and is also responsible for the green color of plants whereas Phosphorus is crucial for the development of seeds and fruits that is major in growing a plant. Option A) this option can be correct as sulfur is an important element for forming enzymes, proteins, vitamins and chlorophyll in plants. It also participates in the growth of crops and is essential in the photosynthesis process but sulfur is not that element which every plant can intake. The plants that do not take sulfur lead to the color of leaves to be yellowish.
Option B) this is an incorrect option.
Option C) this is an incorrect option as this is a gas which is noble.
Option D) this is a correct option as nitrogen helps in the growth of plants.

Note:
We have to know that nitrogen helps in the development of leaves in a plant and it is also responsible for the green color of plants whereas Phosphorus is crucial for the development of seeds and fruits that is major in growing a plant.
