Which of the following is addressed by chlorinating wastewater to control odors?

Explanation:
Chlorination helps control odors by oxidizing the compounds that cause smells, mainly reduced sulfur compounds like hydrogen sulfide and related mercaptans, as well as some ammonia species. When these odor-causing substances are oxidized, they become less volatile and produce fewer odors, so the overall odor intensity decreases. While chlorine also serves to disinfect and kill pathogens, the odor-control effect comes from this oxidation of smelly compounds, not from reducing BOD or suspended solids. So, chlorination addresses the odor itself.
