The false statement about ozone is "It is concentrated in the atmospheric layer called mesosphere."
To know the false statement among the other options, we first need to understand about the ozone layer.
What is ozone layer?
- Ozone layer is found in the upper part of the atmosphere called the stratosphere.
- It basically acts like a sheild in absorbing the UV radiations from the sun.
- Its concentration is decreasing/thining which will cause more UV radiations to reach on the surface of earth, which has many harmful effects on photosynthesis and nucleic acid in living organism.
- This layer is formed by the reaction of oxygen molecule with one nacent oxygen.
- The reason for its depletion is Ozone depleting substances (ODS), which react with it and destroy the same by liberating oxygen molecule.
So, we can say that the answer that suggest ozone layer is present in the mesosphere is false, because it is present in the stratosphere.
