which of the following is the main benefit of ozone?\na. reduces pollution levels\nb. absorbs ultraviolet…

Brief Explanations:

Ozone in the stratosphere forms a layer that acts as a shield. Ultraviolet (UV) radiation from the Sun can be harmful to living organisms (causing skin cancer, cataracts in eyes, and damaging plant and plankton life). Ozone ($O_3$) has the property of absorbing a significant amount of this UV - B and UV - C radiation. Pollution levels are mainly affected by human activities like industrial emissions, vehicle exhausts etc. and ozone (in the troposphere, it can even be a pollutant). Particulates are filtered by other mechanisms like precipitation, vegetation etc. and not by ozone. Carbon monoxide ($CO$) is a toxic gas, and ozone does not neutralize its effects in a beneficial way relevant to its main role.

Answer:

B. absorbs ultraviolet radiation from the Sun
