The answer is letter B. Particles in the atmosphere clearing the surrounding air which did not occur as a result of oil production and distribution around the Persian Gulf. All other choices such as A, C, D happened or occurred as a result of the oil production around the Persian Gulf.
The correct answer is - B. Particles in the atmosphere clearing the surrounding air.
Oil production and distribution in the Persian Gulf has not contributed to the release of particles in the atmosphere that are clearing the air, but the total opposite, it has contributed to increased pollution of the air because of the releasing of huge amounts of toxins and CO2 into the atmosphere and thus significantly lower the air quality. Unfortunately, nothing serious is considered to be done about this issue because everyone just puts the profit on first place, and the environment is always in the background even though its well being is essential for our life, health, and prosper.
