Answer:

(D) They are all acids

Step-by-step explanation:

Amino acids are monomers, fatty acids are polymers and they do not contain nitrogen. All four are acidic in nature for different reasons:

  • Amino acids due to acidic carboxyl group -COOH.
  • Fatty acids due to end chain acidic carboxyl group -COOH.
  • Nucleotides because they have phosphate groups (which are acidic in nature).
  • Monosaccharides due to presence of aldehyde group -CHO (which can oxidise to -COOH).
