B Correct answer

Nitrites and nitrates are inorganic forms of nitrogen that plants absorb from soil and convert into organic compounds. Through nitrogen assimilation, these are reduced to ammonium and then incorporated into amino acids, which are the building blocks of proteins. This process is essential for plant growth and protein synthesis.
