There are different micro and macro nutrients required for the growth and development of the plants. Nitrogen is considered as one of the most important nutrients for the growth. Nitrogen is also involved in the process of photosynthesis. The nitrogen is present in the porphyrin rings of the chlorophyll pigment. There are many enzymes which are involved in the reactions of photosynthesis. These enzymes contain nitrogen. The enzyme RuBisCo which is involved in carbon fixation contains nitrogen

Thus, the correct answer is option B.
