Question

The ozone layer sits near the top of Earth's atmosphere and protects us from the sun's harmful ultraviolet rays. But ozone is dangerous when it's closer to ground level. Which of the following describes ozone?
Select one of the options below as your answer:

A.
a fibrous mineral used to insulate and fireproof buildings and home appliances that can cause lung cancer when inhaled
B.
a radioactive gas that can enter a house through its foundation and produce indoor pollution that can cause lung cancer
C.
a combination of nitrogen oxides and volatile organic compounds present in various emissions that can irritate respiratory organs

Answer 1

"A combination of nitrogen oxides and volatile organic compounds present in various emissions that can irritate respiratory organs" is the one among the following choices given in the question that describes ozone. The correct option among all the options that are given in the question is the third option or option "C". 

Answer 2

Correct answer choice is :

C) A combination of nitrogen oxides and volatile organic compounds present in various emissions that can irritate respiratory organs

Explanation:

Ozone is formed in the environment when the sun's rays cut oxygen molecules into individual atoms. These atoms connect with nearby oxygen to form a three-oxygen molecule, called ozone. Even as it's being made, ozone is also damaged by sunlight and effects including natural composites that include chlorine, nitrogen, and hydrogen. The ozone layer or ozone shield is a range of Earth's stratosphere that consumes most of the Sun's ultraviolet emission. It includes high frequencies of ozone (O3) in connection to other parts of the atmosphere, although still small in connection to other vapors in the stratosphere.
