A Correct answer
Explanation

Monomers are the smallest repeating units that join together through polymerization to form large polymer chains. For example, ethene monomers join to form polythene. 'Repeating unit' refers to the unit within the polymer chain, not the starting molecule, and 'dimer' means only two units bonded together.
