Answer 1

Hint: You know that, we all are dependent on air for our respiratory needs. Air pollutants can induce injury to all living organisms. Air pollution decreases yield and growth of crops and causes premature death of plants. They also dangerously affect the respiratory system of humans as well as of animals. Harmful effects of air pollution depend on the concentration of air pollutants, exposure duration to them and the organism.

Complete answer:
You must know, Air pollution is a mixture of gases and solid particles in the air. Ozone is a gas and has a big role in air pollution in cities. When air pollution is caused by ozone, it is referred to as smog.
Remember, The Chernobyl disaster was a damaging nuclear accident, which occurred on 26 April 1986, in the No. 4 nuclear reactor at the Chernobyl Nuclear Power Plant, located in the north of the Ukrainian SSR. This incident led to accidental leaking of radioactive wastes into the surroundings that resulted in a large number of loss of human life and caused many genetic disorders because of radioactive mutations.
The El Niño, is a kind of climate pattern that shows the unusual warming of surface waters in the eastern tropical Pacific Ocean. It is the “warm phase” of a larger phenomenon referred to as, the El Nino-Southern Oscillation (ENSO). El Nino results in climate change.
Now let’s discuss Chlorofluorocarbons (CFCs), they rise slowly upward to the stratosphere, are broken up by UV radiation, and give chlorine atoms. CFCs are made up of chlorine, fluorine and carbon atoms. When these Chlorofluorocarbons are released into the atmosphere and reach up to the stratosphere by strong winds and UV radiation from the sun hits the Chlorofluorocarbons molecules. This interaction results in chlorine atoms breaking apart from the chlorine molecule and these molecules are able to destroy ozone molecules.
You should know, Snow blindness is temporary loss of vision. It is painful, because of overexposure to the sun's UV -B rays. Snow blindness symptoms include inflammation of the cornea.

Therefore, the correct answer is 'a, b, d' (Option C).

Additional information:
It’s important to note that long-term health effects of air pollution are heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also result in long-term damage to people's nerves, kidneys, liver, brain, and other organs. It is suspected that air pollutants cause birth defects.

Note:
Always keep in mind, the Increase in greenhouse gases level has led to heating of Earth leading to global warming. Remember, the ozone hole over Antarctica develops every year between late August and early October. Courtesy: NASA three decades. It is believed that rise in temperature is leading to damaging changes in the environment that result in odd climatic changes (example- El Nino effect), which leads to increased melting of polar ice caps as well as of other places like the Himalayan snow caps. Over many years, this will lead to rise in sea level which can submerge many coastal areas.
