The correct option is A Amylase
Amylase is peptide hormone and consists of amino acids as monomer subunit. Glycogen is homopolysaccharide of D-glucose while lipids having attached phosphate groups are called as phospholipids. Polysaccharides are polymers of simple sugars (single polyhydroxy aldehyde or ketone unit). Ribonucleic acid is a polymer of ribonucleotide monomers. Thus, the correct answer is A.
