ACatalyst
BPolymer
CIsomer
DMonomer
Answer & Solution
Correct answer: B. Polymer
1. Macromolecules are built by joining many small units in a regular manner.
2. The repeating small unit is called the monomer.
3. The large molecule formed by regular repetition of that unit is called a polymer.
4. Rule out D: the monomer is the small repeating unit, not the whole large molecule.
