The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Question**: The question asks which component in the stratosphere absorbs UV radiation. 2. **Review the Options**: The options provided are: - A) Oxygen - B) Ozone - C) Argon - D) Sulphur Dioxide 3. **Analyze Each Option**: - **Oxygen**: While oxygen is essential for life and present in the atmosphere, it does not significantly absorb UV radiation. - **Ozone**: Ozone is found in the stratosphere and is known for its ability to absorb UV radiation from the sun. It forms the ozone layer, which is crucial for protecting life on Earth from harmful UV rays. - **Argon**: Argon is an inert gas present in the atmosphere but does not play a role in absorbing UV radiation. - **Sulphur Dioxide**: Although sulphur dioxide is found in both the troposphere and stratosphere, it does not absorb UV radiation effectively. 4. **Determine the Correct Answer**: Based on the analysis, the component that absorbs UV radiation in the stratosphere is **Ozone**. 5. **Conclusion**: The correct answer to the question is **B) Ozone**. ---

Ozone in the stratosphere is deleted by

UV radiations bring about

Ozone makes the stratosphere

Assertion (A) : Ozone is destroyed by solar radiation in upper streatosphere. Reason (R) : Thinning of the ozone layer allows excessive UV radiations to reach the surface of earth.

Ozone in stratosphere extends

With the depletion of ozone layer more UV radiation filters into the troposphere. UV radiations lead to :

When heathly earth's stratosphere contains a low concentration of ozone (O_(3)) that absorbs potentially harmful ultraviolet (UV) radiations by the cycle shown below: Chloroflouro carbon refrigerants, such as freon 12(CF_(2)Cl_(2)) , are stable in lower atmosphere but in the stratosphere, they absorb high energy UV radiation to generate chlorine radicals. CF_(2)Cl_(2) overset(hv)(to) CF_(2)Cl+Cl The presence of small number of chlorine radicals appears to lower ozone concentrations dramatically. The following reactions are all known to be exothermic (except the one requiring light) and to have high rate constant. A:Cl-O-O-Cloverset(hv)(to)O_(2)+2Cl^(*) B: Cl_O^(*)+O to O_(2)+Cl^(*) C:Cl^(*)+O_(3) to Cl-O^(*)+O_(2) D:2Cl-O^(*) to Cl-O-O-Cl Q. Ozone has the ability to absorb
