The correct answer is d. Ozone.

Here's why:

a. SO2 (Sulfur Dioxide) - This gas is not safe at any level. It can cause respiratory problems and is also a key player in the formation of acid rain.

b. CO2 (Carbon Dioxide) - This gas is generally safe for humans to breathe in small amounts. However, in large amounts, it can displace oxygen in the air, which can lead to health problems. It is also a major contributor to global warming.

c. NOx (Nitrogen Oxides) - These gases are not safe at any level. They can cause respiratory problems and contribute to the formation of smog and acid rain.

d. Ozone - This gas is safe and indeed essential in the stratosphere because it absorbs most of the Sun's harmful ultraviolet radiation, protecting life on Earth. However, at ground level, it is harmful to breathe and can cause a number of health problems. It is also a major component of smog.
