Solution
The correct option is A Ultraviolet ray Good ozone is found in the upper part of the atmosphere called as the stratosphere, and it acts as a shield absorbing ultraviolet radiations from the sun which are highly injurious to living organisms since DNA and proteins of living organisms preferentially absorb UV rays, and its high energy breaks the chemical bonds within these molecules.
