Option 4 is right option regarding incorrect association.
A nucleotide is a monomer made of sugar, base and phosphate group whereas nucleic acid is a polymer of nucleotide. Thus, this association is correct.
Amino acid is a monomer such as glycine, alanine whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.
Monosaccharide is a monomer such as glucose, fructose which associates together to produce polysaccharide such as cellulose made from glucose.
nucleic acid is a polymer of nucleotide whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.
Thus, option 4 is right option having incorrect association.
