Out of the following given choices;
A. Monomers in a polymer could be linked in various ways.
B. Monomers in a polymer are of different types
C. Monomers in a polymer look different but are structurally similar.
The answer is A. The multicolored necklace analogy means that the polymer is composed of different types of monomers. They, therefore, could also be linked in various ways. An example of this type of polymer is synthetic nylon and polyethylene, or phospholipids and oils in biology. If the monomers making the polymer are of one kind, then the best necklace analogy would be that it is composed of the same colored beads.
