Apolymer contains monomers linked by
a. ) ionic bonds
b. ) covalent bonds
c. ) polyatomic ions
d. ) hydrogen bonds

The correct answer is

B) Covalent Bonds.

Explanation:

A chemical reaction bonding monomers commonly to make a polymer is called polymerization. Some polymers are physical and created by organisms. Proteins have polypeptide molecules, which are natural polymers made from various amino acid monomer units. A particular polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure. Covalent bonds hold the atoms in the polymer molecules together and formed bonds then hold groups of polymer chains collectively to form the polymeric material.
