Question

Which of the following is not dangerous for life?

• A. Nuclear blast
• B. Deforestation
• C. Ozone layer
• D. Biopollutants

Answer 1

The correct option is C Ozone layer

Ozone layer is part of earth's atmosphere. Ozone is basically found in stratosphere. Ozone layer contains high concentration of ozone formed due to reaction of oxygen with UV radiations. It is vital to human life on earth because it absorbs biologically harmful ultraviolet radiations from sun. Direct exposure of such rays can cause serious illness and skin problems. However ozone chemically forming in earth's surface is lethal in many ways.

Hence, the correct answer is 'Ozone layer'.
