Question

the structure shown is comprised of which monomer? options: guanine, glucose, alanine, lauric acid

Explanation:

The structure shown is a polysaccharide (like glycogen or starch), which is a polymer of glucose. Guanine is a nucleotide base, alanine is an amino acid, and lauric acid is a fatty acid—none are the monomer of polysaccharides. Glucose is the monosaccharide monomer for polysaccharides, matching the branched/polymeric structure here.

Answer:

B. Glucose
