Detailed explanation-1: -A monomer is a molecule of any class of organic compounds that can bind chemically to the same molecules or other compounds to form a large molecule or polymer containing large number of repeating units of monomers.

Detailed explanation-2: -Organic polymers are macromolecules composed of many repeating monomer units. Both synthetic and natural polymers play a crucial role in everyday life. Polysaccharides, polypeptides, and polynucleotides are the main types of biopolymers in living cells.

Detailed explanation-3: -Organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. All the options are true about Organic compounds except option I, Organic compounds does not contain calcium. They are molecules that contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

Detailed explanation-4: -The polymers can be classified as organic and inorganic polymers. It is well known that organic polymers consist primarily of carbon and hydrogen atoms and frequently along with some heteroatom such as oxygen, nitrogen, and sulfur.
