Ozone gas is present in which layer of atmosphere?

 The correct answer is Option (1)- Stratosphere

Ozone gas is present in the Stratosphere layer of the atmosphere.

Explanation:

• The Earth's atmosphere is divided into several layers, including the troposphere, stratosphere, mesosphere, ionosphere, and exosphere.
• The ozone layer is primarily located in the stratosphere, particularly in the lower portion of the stratosphere.
• Ozone (O3) in the stratosphere plays a crucial role in absorbing ultraviolet (UV) radiation from the sun, providing protection to life on Earth.

Therefore, the correct answer is Stratosphere.
