Right option is (b) False
Explanation: Polymers consists of thousands of repeating units, and are macromolecules because of their very large size and high molecular mass (10^3 to 10^7 u). However, a macromolecule may or may not contain repeating monomer units (for example, chlorophyll). Therefore, all polymers are macromolecules, but all macromolecules are not polymers.
