The better description of the structures of carbohydrates is Option B They occur as monomers, chains of monomers, and branched structures.

  • Carbohydrates can be divided into monosaccharides (simple monomers), disaccharides (composed of two monosaccharides), and polysaccharides (long chains of monosaccharides) depending on the number of monomers that form the molecule.

  • Carbohydrates are simple or complex structures composed of carbon (C), hydrogen (H) and oxygen (O).

  • Simple carbohydrates include both monosaccharides and disaccharides such as glucose, fructose, and lactose.

  • Complex carbohydrates are polysaccharides that may be branched or not branched (e.g., starch, glycogen, amylopectin, cellulose, and chitin).

In conclusion, carbohydrates can be monomers, chains of monomers, and branched structures (Option B)
