Answer :
The correct option is D. loss of electrons.
Loss of electrons is the statement best describes the process of oxidation.
Chemical reaction known as oxidation is described as a procedure that takes place when atoms or group of atoms lose electrons. If a chemical species gains oxygen or loses hydrogen, that is an example of oxidation. Oxidation takes place when these things happen.
An oxidising agent is any substance that causes another chemical lose electrons (become oxidised). On the other hand, a reducing agent is any chemical that causes another chemical to gain electrons.
The biochemical oxygen demand of wastewater is reduced after oxidation, which also reduces some contaminants' toxicity. Some contaminants undergo this treatment and are transformed into carbon dioxide, water, and biosolids. Disinfection is frequently accomplished using chemical oxidation.
