During the formation of addition polymerization, which smaller molecules you think are eliminated:

Explanation

Addition polymerization involves the joining of monomers without the loss of any small molecules, which is a key characteristic distinguishing it from condensation polymerization. During addition polymerization, the entire monomer becomes part of the polymer chain, and no other substances are formed. This is why the correct answer is that 'No molecules are eliminated.'Options A, B, and C describe molecules that are typically eliminated in condensation reactions, where small molecules like water, HCl, or NH3 can be byproducts. These processes are different from addition polymerization, where such eliminations do not occur.
