The statement "Amino acids contain nitrogen; fatty acids and sugars do not" is the most accurate response that highlights what makes amino acids unique from fatty acids and sugars.
Amino acids are the building blocks of proteins and are distinct from fatty acids (which consist primarily of carbon and hydrogen and are components of lipids) and sugars (which are carbohydrates). The presence of nitrogen in amino acids is a key differentiator, as fatty acids and sugars lack this element.
