Correct answer
BOxidising smog

Step-by-step explanation

In presence of ozone O3, oxidising smog gets increased during the daytime because automobiles and factories produce main components of the photochemical smog (oxidising smog) results from the action of sunlight on unsaturated hydrocarbon and nitrogen oxide.
