Selection: Among the following explanations of related terms, which one is incorrect? ( ) A. Substances that deactivate free radicals are called polymerization inhibitors; B. Substances that can deactivate some free radicals or reduce their activity are called retarders; C. Free-radical polymerization refers to a chemical reaction in which monomers are activated into free radicals through the action of light, heat, radiation energy, initiators, etc., and then these free radicals undergo chain polymerization with other monomer molecules to form polymers; D. The initiation efficiency of an initiator refers to the number of primary free radicals produced by the decomposition of the initiator compared to the actual amount of the initiator used for initiation
