The correct option is D I, II and III

The building blocks of lipids are fatty acids linked by ester bonds. They are not made up of amino acids. Amino acids form peptide bonds with each other to create proteins.

Haem is the non-protein part present in haemoglobin, it's not present in all enzymes. The non-protein part in different conjugate protein differs from one another.

Galactose is a monosaccharide, which combines with glucose to produce disaccharide lactose. Sugar cane is the result of fructose combined with glucose .
