The correct answer is option 3, which states that both statement 1 and statement 2 are correct.

Statement 1: It absorbs most of the ultraviolet radiation found in the Sun’s rays.

The ozone layer plays a crucial role in absorbing and filtering the majority of the Sun`s ultraviolet (UV) radiation. This helps to protect life on Earth from the harmful effects of excessive UV radiation, which can lead to skin cancer and other health issues.

Statement 2: Chlorofluorocarbons are a serious threat to the ozone layer.

Chlorofluorocarbons (CFCs) are a type of synthetic chemical compound that was widely used in aerosol propellants, refrigerators, and air conditioning systems. CFCs have been found to have a destructive effect on the ozone layer. When released into the atmosphere, CFCs can reach the ozone layer and break down ozone molecules, leading to ozone depletion and the formation of the ozone hole. This has serious environmental implications, as a depleted ozone layer allows more UV radiation to reach the Earth`s surface.

Therefore, both statement 1 and statement 2 are correct, and the correct answer is option 3. There is no need for an alert in this case.
