What does COD stand for in the given material?

Explanation:
COD here stands for Chemical Oxygen Demand. This is a standard term in environmental and process engineering that describes the amount of oxygen, typically measured in milligrams per liter, that would be needed to chemically oxidize organic matter in water. It’s a key indicator of how much organic pollution is present and helps gauge treatment effectiveness and wastewater quality. The other options don’t fit typical engineering usage in this context. “Control of defeat,” “Correction of deviation,” and “Code of data” aren’t established terms related to water quality or process monitoring, so they don’t align with what COD represents in this material.
