Ozone is the atmospheric gas that protects life from being scorched by the sun’s intense ultraviolet rays. Most of this gas is concentrated in the stratosphere, forming the ozone layer. It acts as a biological shield, absorbing high-energy radiation that would otherwise cause skin cancer, cataracts and damage to various ecosystems, ensuring the planet remains safe for all living organisms now. ANSWER: (A) Ozone

The ozone layer, located primarily within the stratosphere, plays a critical role in safeguarding the Earth’s biosphere. It functions as a protective filter that absorbs nearly 99% of the sun’s harmful high-frequency ultraviolet radiation. Without this gaseous shield, the intense energy from the sun would cause severe biological damage, including DNA mutations and the destruction of microscopic marine life. Ozone molecules are constantly created and destroyed in a natural cycle, maintaining a delicate balance that regulates the amount of solar energy reaching the surface. Protecting this layer is vital for maintaining the health of all terrestrial environments.
